Lmao they don’t make ‘em anymore and Amazon doesn’t sell them. Just called Ford and it sells for $160 for the whole assembly. Found the rubber elbow at Napa for $30. This video helped a lot. Thanks dude.
Well, You saved my ass again! 4 years ago I followed the 4 part video of timing chains in my 1998 Explorer 4.0 SOHC motor and its still going strong. Now I went back to your videos because I had the P0171 & P0174 codes. Been working on it for a week. Tried the relearn strategy, Still ran up and down. Watched your video and sure as shit that was the problem. Changed out the hose, Test drove it and no more racing engine or dying at a light. It was so bad that sometimes coming to a stop light the tranny would bang so hard. And yes I did do something stupid, I changed the IAC motor thinking that was the problem. Your the best!! Subscribed to you for 4+ years now!
I had a rough idle in my 2003 Explorer. One of my best friends, who is a certified Ford mechanic, pulled the codes and insisted that it had a cracked intake manifold. After checking the video, I located the rubber elbow and sure enough.. It was the exact same split. Since it was a Sunday and I am 2 hrs from a parts store... I cut a piece of washing machine hose and Voila!!!! Fixed!!! I then disconnected the battery for 15mins and the Check Engine light reset itself. Thank you very much.. All is good again!!!!
FordTechMakuloco i have a 96 4.0 acting the same way but im not finding it on the side you are in the vid is there a different set up also? I found something similar on the other side
i am hearing the air ,why i havent gotten to it yet ,lol. ,reset the code pull neg ground off battery place a piece of cardboard under clamp to insulate from reconnection.using a wire w/alligator clips on both ends touch the ground cable to the hot cable and battery post 5 seconds.only way to erase memory according to one video .good video i havent gotten to the leak truck is gonna be fixed soon i am sure of it now cause i heard real air leak and my idle mostly is problem almost like gurgling
Thank you so much! My 2002 Explorer would not run on its own while idling and found the problem in less than a minute of having the hood up. My elbow was disconnected from the hard tube. Popped it back on and put a hose clamp on it for now. You're the best!
Here is one on this problem that no one that I have watched covered. I had rough idle a PO171 code and stalling when put in gear, I check every sensor looked high and low for a vac leak watched over a dozen video and could not find my problem. everything checked out as good final we figure it out a clogged fuel filter was not allowing enough fuel to get to the engine a long day of pulling out our hair ended with the very simple and cheap fix of a new fuel filter. The one important lesson I learned was start with the basics and branch out from there.
Thank you so very much, your advise enabled me to locate the elbow and find that it had completely detached from the engine, reconnected and idles perfectly.
More Explorer vids please. Trying to keep mine on the road it's a 94 Fort Explorer Eddie Bauer 4x4 4.0L it has 312,000 miles I love it and I learned a lot about motors
Is that thing still on the road?? You have the OHV or the Dohc like he does? I got a 97 ford explorer OHV and im at 366xxx km and just replaced the head gasket but now im getting engine too lean codes but im hoping its just my hoses or a broken o2 sensor
OMG. I had gotten a diagnosis of intake manifold leak. I was prepared to just scrap my '03 Sport Trac. YAY! $120 fix from my shop and I'm back in business. THANK YOU!!
Changed out the valve gasket on my wife's 2008 Ford Fusion today. Did exactly what you said in your video, felt very confident. The job took me close to an hour. Took my time taking everything apart and cleaning/ inspecting. Waited for about 4 hours for the RTV to cure, then ran the engine to operating temp, found no leaks. Went for test drive and double checked the valve cover for leaks. Wonder how much a mechanic would charge me for this job! Excellent job on your video!
Thank you. I had to clear 4 error codes so my GF's 01 Ford Explorer Sport would pass emissions and I did not notice this cracked tube when I was diagnosing the last two 0171/0174 error codes until I watched your video.
My 2003 Ranger 4.0 never had a rough idle just a sudden CEL for P0171 and P0174 lean codes. I checked my PCV elbows and didn't see any cracks or holes. I pulled the front elbow, the one in your video, and found a small hole on the underside. I replaced it with a elbow I had, cleaned the MAF and cleared the codes. I hope this fixes the issue.
OMG you just solved a problem for me that I have been looking for for about 4 months now. Although I am a female I know a little bit about cars just not enough and I've done everything but that! wow, I wish I would have found you sooner, I have found you now and yes I subscribed, thank you so much you was truly a godsend for me right now and thank you so much for the great detailed instructions, us women truly appreciate that!
I own a 2008 fx4 4.0 ranger that I purchased about four months ago and im just trying to get as much information as I can about these motor, I'm a new subscriber, thank you for your helpful videos
I have an '03 Sport Trac, My truck was wanting to die while sitting at idle for a long time. I came across your video, while searching for how to change the O2 sensors. I went and checked the elbow, and low and behold, the elbow had a split in it. The only thing I was hoping for in this video is showing the exact placement of the complete hose, removal and install. This video just saved me $300. Mechanic didn't even check the elbow, just went by the codes and insisted it was the O2 sensors.
ill try not to be long winded here but in a nut shell, every thing you stated regarding the codes, symptoms cause and repair were exactly what i found, so thank you,
Thank you for posting this. I was having a rough idle and noted the P0171 & P0174 lean codes, When I looked at the hose, I was surprised to see that it looks almost identical to your cracked hose. You have saved me some major headaches. Thank you.
I miss my OHV 4.0. 174,000 miles and still didn't have to do any repairs. Still ran like new, ran better than my cousins POS chevy s10 4.3 with 180k. White smoke, crusty oil residue, ran hot even with a good cooling system. Burnt oil too and started getting rod knock.
Thank you very much for this info. I have a similar setup on my 2002 Ford Ranger XLT 4.0L. One design I don't like is how the PCV has to be mounted to at port at the end of the Left Valve Cover. A Mechanic had cracked that PCV mounting port off the valve cover and it cost me plenty to have that valve cover replaced. So, for me that PCV can be very costly to changeout, if I have to change the valve cover too. I changed lots of PCV valve, but I don't want to change this one.
Another reason it could be hunting for idle other then PVC or TPS or IAC on cold starts is the Timing chain tensioners, there are 2 of them an upper and lower..this was my case.
Great tip. I've had my '03 SportTrac since '05....Pretty decent and dependable vehicle. Replaced this a couple of years ago. You're exactly right, from my experience dealing with mine, really just small components fail from regular wear and tear. The most annoying things were the emergency fuel shut off, and that darn t-stat housing (X3), With regular maintenance the hard stuff been held at bay so I've been happy. My wife just bought a '14 Explorer 3.5 V6. We'll be lucky if it's any where near as good of a vehicle.
Thank you for your videos, they are very helpful. Ok,,, 2 things here. 1st, this is slightly different info here. I have a Ford Explorer 1998 4.0, my PCV valve is way in the back of the engine. It took me a while to locate it. It's also very hard to get to it. Also, Thank you Todd Picklyk, That was very helpful info, disconnect the battery for 15 minutes and it will clear the check engine light.
Encountered this exact same problem on my cousin's C5 Corvette. Very similar design, and it collapsed in the same way. Idle was hunting and rough, stalling occasionally. Was hard to find because the intake tube opening is pretty close to the throttle body on those and it masked the sound. Replaced the broken elbow with a scrap length of fuel line I had in the shop as a temporary fix. That was about a year ago. Still running fine that way.
Love the channel it's already saved me a butt load of money!! I'm not a huge Ford fan but seems I'm always stuck in one😫so this is really helping me out I'm having a code come up for 02 sensor bank 2 that I suspect is a bad cat or 🐈 🐈 🐈 I'm really wanting them deleted but don't want the bad sounding exhaust or codes still looking for a good cat delete video where everything turns out ok!!
Do you think an imperfect valve cover gasket could cause the codes also? I know it needs to be replaced but I’m hoping the codes will go away after I change it.
Mine's somewhere between rattle out and just old and decrepit.... Hopefully it's warm enough before work tomorrow to get hunting for the individual cause... I know one is near the power steering and transmission cases, and there's gaurenteed a few other connections from how long it's had this bad fan in there for.... Dang ol previous owners
Thank you for taking the time to make this video. I have a 2001 sport trac with the 4.0, and I have been hunting a idle issue for almost a year. From what I understand there is a job1 and 2 for these engines. And I cannot find this hose on my engine, I do see the plastic hose that goes to the rear of the valve cover, but no rubber hose on the front of the engine. Do you have any idea's for my engine? It runs ok, but sometimes when you put it into gear it will actually die, and start back up again after restarting the engine. I am getting horrible mpg at only 13 mpg, and have been for almost a year. This thing is driving me nuts. I have cleaned everything you can think of, and you could eat off of my engine. I am crazy about maintaining my vehicles so any oil leaks are fixed as soon as found. But this vacuum leak has been evading me. Any help would be greatly appreciated, one last thing the truck is not throwing any codes and never has. Thanks again.
@@SBS_Auto I purchased it with low miles almost 20 years ago now. I did finally figure it out, the problem was the idle control sensor I think it was called. It's right on the top of the intake in the center. Took about 3 minutes to switch out and it's ran perfectly.
Hey Brian, I am most likey off topic here, but I'd like to know how to get a good front end alignment, repair/replace child door locks and headlight alignment. was given 2000 explorer XLT. You could say a rolling dumpster, it was and still is in need of a lot of TLC. Yesterday the engine ran erratically, and died when wife drove to work. She thought it may have been overheated. She added 50/50 mix antifreeze and it appears to be ok. However, after viewing video, I will check that tomorrow. I am unable to drive, and apprehensively must ride in it to Dr.office. It seems squirrly on the road, one slight overcorrection scares me a bit, much like a willis army jeep. Is this because of the wheelbase being short or incorrect tire size? All 4 are the same, just smaller. Thanks for videos, and your time/expertise.
My explorer does the idle up/down surge only in the winter, but not the summers... Would this be the problem? I'm not near it right now so I can't check it... but I was told it was the IAC also. Before I get parts and drive to it could you reply?
Have you ever replaced the fuel rail pressure sensor on this particular vehicle-in the video? I'm trying locate the sensor on my 2003 Sport Trac (4.0 OHV) but I can't find any videos covering my model year(2003). Any help is greatly appreciated---thanks.
I recently bought a 96 explorer. It appears as though I either don't have the same elbow or I am struggling to find it. My engine scavenges at warm idle and I believe I hear a faint hissing, it also is throwing a P0133 code. Tried spraying carb cleaner around the entire intake manifold and vacuum lines and didn't detect any change in idle. Any help or ideas would be great! Thanks.
It would of been nice to actually watch you replace it, you say easy to just fish it out but I would like to see and where it goes it back, best way to get to that PCV valve and show to replace the valve, cant find 1 video...PLEASE post one if you could, definitely be much appreciated!! Thanks
I have an 2001 ford explorer sport track 4.0 v6 I have replaced maf, idle control. It sits at idle then dies, check engine light on. I went and had it checked it said running to rich.
i spent hundreds of dollars on lucas high milage. additives. oil stablizers. car runs silentlike a prius. and its as 2003 ford explorer with 226k miles with a new tranny new radiator new water pump new starter new spark plugs new bAttery. welded exhaust . new tires brakes rotors calipers and oil changes at 2500k ....
Great Video I have a 2000 Ford ranger 4.0 with it showing a P0171 lean condition bank one Check Lite... once every 300 or 600 miles .. The truck is running good... only one time it would not idle . Could it be a Fuel Pump going bad? Over all the truck is running great .
gotta 98 ranger 4.0 been babied and is mint 100k miles, I just started getting 171 174, checked pcv valve hose fine, I smoke tested , sprayed brake clean, and tried propane when cold and warm and no change to engine speed but short and long trim stay in 25% range when I take it and and give it gas long term dives to zero. Fuel pressure 65psi, new fuel filter I dont want to change intake gaskets Unless I have sure reason to. Or is that the only option for vacuum leak in this engine, Maf reads fine, and so do O2 sensors, no exhaust leaks, what would you try next.Your the best on the net!
Assume! Nailed it! My 03 Ranger XLT suddenly started running rough, nearly dying while idling and unable to rev over 2000 will accelerating. Seemed like it was running out of gas; it was not. Then started running better after. No check engine lite and no codes. Change fuel filter, checked fuel pump related fuses and relay. Everything OK. Just drive it. Now, two weeks later, it throws two codes: P0171 and P0174, right and left banks lean. The Chilton manual is pretty much useless for this so did a google search for Ranger P0174 P0171. Bingo! The first hit was not quite right so checking the other hits lead me to your video. Great video and thanks for the tips.
Hi. I have a 2000 Mercury mountianeer 4.0 soho engine. I have a pretty rough idle. No DTCs. Fuel trims are ok, long term is adding a little more than normal. I checked my pcv and it's not leaking. My PCv is in a different location than this video though. Any thing common with these? Sort of hunts. Only rough at idle. Minor contribution hits on most cylinders.
I haven’t got my codes checked but I have a 95 explorer and I believe it is the same problem I changed the spark plugs and still was running funny so I’m hoping it is a vacuum leak
great easy explanation of this repair... Question.. I have a 01 explorer 4.o sohc and I am getting a jumping tach needle. I can not find anyone who has a answer for it.. it will sit at idle then start bouncing around... Any clues?
I just subscribed I have a 1998 ford ranger 4.0 liter v6 xlt 4x4 I got the p0171 p0174 codes could I have the same problem as in this video I have rough idle
I have a 02 f150 5.4l sohc wont rev over 2000 rpm when at full operating temp just put in new plugs injectors and coils I removed cats and still doing it fuel pump and fuel filter brand new also
If my 1998 Explorer sits up for a few days when i need to repair it, I'll start it and get a strong exhaust smell coming out of the front of the engine that kind of dies down after a few days, but not all the way, and before it sits up I smell burning metal from the front !!
I have a 2002 Explorer with the same problem. I bought the PCV elbow tube {Motorcraft KCV190}. The other problem I am having is, I can't seem to located where it goes.
I've a,94 explorer xlt.4.0 I'm having issues with my rpms going up. Then down. It's starts very good. I've been told the power brake booster could be the culprit but darn like you said. All these parts can't just go out I'm not ready to sink much more.. Any suggestions
laschell59 If you truly have a large vac leak like I think you do then you can just take off each vac line and plug the port to see if the problem goes away.
I just did a top end job on my '99 Explorer 4.0L SOHC (heads replaced, every gasket and o-ring, timing cassettes, tensioners, chains and sprockets, etc.) and now my brake booster is leaking vacuum. It's running rough at idle, but no codes. Whenever I disconnect the line running to the booster and put my finger over it, the engine continues to run rough. I did have 90 psi compression on #1 cylinder, but I believe it was a stuck ring. Compression is now around 150+, so I know it isn't that. I haven't checked the PCV yet, so I'm going to give that a shot next. Any tips on what else can be causing that?
Thank you Brian, With 2003 Sport Trac V6 4.0L what must I do to re-tune or adapt for flex-fuel...?? By "flex fuel" I mean using any combination of Gasoline, E10, E15, E30, E50, E85, or pure straight ethanol....{in a just pump and go fashion}. Since or local stations now put in random amount of ethanol I never really know what I am running.. E85 might be E50 .. Pure Gasoline does not really exist at most stations in Missouri {due to government mandate to add ethanol/alcohol}.
So I just got my check engine light for these codes on last night. And this morning I was looking around my engine and I realized the part that you showed me that had the hole in it was actually just disconnected from the tube so I reconnected it but my engine light still on?
When I startup my 1995 ford explorer it over idles like it idles almost to 2000 rpms and then it would go down and when I drive it over idles to what could be the problem?
I have a 2008 ford ranger 4.0. , I'm replacing spark plugs with motorcraft plugs that originally were in. Is it recommended to provide anti seize compound on the plugs , if so what brand ?
My fiance 99 exsplorer 4.0 has been fixed twice and still runs rough so any suggestions if I check the tube and it's not that. I've worked on cars years ago but not these often. I'll check the line soon and hope it's this since she's paid the guy over 300 already once a tune up and today 200
Hey I have a 1999 ford explorer 4.0 / 2 wheel drive the oil gage started bouncing around today and 30 min later it started a knocking noise I changed the sensor already and it's still doing it.. The knocking makes me think it's the oil pump can you tell me your thoughts on this and if you think it's the oil pump what's the easiest way to change the oil pump??? Thanks in advance
Aaron Stoner if it started knocking then an oil pressure test is in order if it its low you need to look at the oil pump drive under the cam synchronizer first then go after the oil pump. How is the oil level?
FordTechMakuloco I Drive a 1997 Lexus es300 I change the mass air flow sensor the PCV valve to Idle Air Control i change coils & the spark plug and everytime I go over 80 miles an hour the car. Rpm idle pooly whan i come to a stop
hey this video helped me with a start to my problems. I have a 2001 ford explorer sport Im also throwing codes p0125, p01121 im having a hard time with these can you help!?
Hey! Good evening. I have a 2002 explorer 4.0 with a new engine with no more than 4K miles on it and my rear timing chain has a bit of a noise, I’m wondering if I can get away with replacing that external tensioner. Not sure why my new engine would have any noises at such low miles.
hi you helped me out before i have an used 2005 ford 500 limited and never changed the wipers before one was have gone went to change the wipers at advance auto and the guy told me he aint never seen a nut on each one to hold it on and said i might have to replace the wiper arm and i want to know do i have to changed the wiper arms to get the right end pieces to lock the wiper blades in instead if the silver nut please help have pictures and don't know how to post pictures on here
It seems the arm has been botched yes, all wipers clip into the arms no nuts or bolts required. I would change the arms out and some new blades and you will be all set with the correct arms and tension so you have good clearing of the windshield for the upcoming fall rainy season and winter snow.
Why does ford have two different style Upper Intake manifolds for the SOHC for these model years. Like mine is two huge double barrel things and this one looks like what most rangers have. My last explorer which was a 2000 XLT is same as my 2001 Explorer 2 door Sport which has same front end as a Sport Trac because for some reason they couldn't decide on that either.
I thot some of the readers might want to know, if you happen to accidentally switch plug wires 5 and 6, you will get a P0174, high long and short term fuel trim bank2 only, and loss of power, but no check engine light, and no backfires, runs only a little rough,, ask me how I know :) the correct cylinders are noted on top of the coil , very faint on this vehicle but i was able to find them
I have the exact size motor in my Explorer, but its 2000 model. My oil pressure gauge is going haywire and there is some ticking in the motor. I love my truck. So I parked it. Do I need to just replace it..or is there a not too expensive resolution...??
Hi I have 2006 Mercury Mountaineer, recently I am facing a problem with shifting of gears, loose /free shifting, and not engaging to the selected gear, some times gets engaged after a minute. Power train malfunction indicator shown in instrument cluster. could you suggest the real cause of this issue and how we can tackle it. thanks in advance.
I have a, 07 explorer, 4X4, 4.0L with just over 80,000 miles, that runs rough idle and dies after I have driven her for a while gotten her up to running temperature and shut her off, resting for 2 - 30 minutes and then try to restart her. I have changed my throttle body, MAF, intake manifold gaskets, (caused they leaked) and still have the same issue. Codes come up with a p1000, but that is no big deal, and had a B1676 error pop up, but I do not know if that has anything to do with the engine running rough, I have no idea. The only thing I can think of after this is spark and fuel. According to my scanner my fuel is now with in normal range, which leaves spark. I was thinking about changing out my ignition system, Spark plug wires and spark plugs. What do you think.
need your help. what is the piece called. on a 2004 Ford explorer. not the radiator but behind it. there are 2 hoses that connect to it. right above the drain plug of radiator. It's the one right behind the radiator, thank you.
I have a 2008 Mercury Mountaineer and I just replaced the thermostat housing and the intake manifold gaskets. Now that it is all back together it I am having a very rough idle/misfire. I took the intake back off to investigate and there is now oil in my intake at one of my cylinders. Could this oil be caused by a manifold leak, which would be causing the misfire/very rough idle? Tricks on getting the intake manifold to seat well? thank you
I have a 1999 ford explorer sport, does its spudders when you make a complete stop it will spudder here and there like it wants to turn of but doesn't the idle barely moves when it spudders , put it in park a leave it for a while like a minute and it tuns off byitself?
Thanks for all your helpful videos! I have a 2000 Explorer Eddie Bauer 4.0 SOHC would this be the same design and replacement part as the sport track? I clicked on your ebay link and it claims the elbow fits my vehicle but I just wanted to double check. Wasnt sure if the design was different in the prior gen 4.0 SOHC. Thank you again!
Really enjoying your videos. Ive got a 2006 4.0 explorer with rough idle as well as when cruising at around 1400 to 1700 rpm the engine feels like it misses which is an annoying uneven ride and no problems when foot down on the gas. Could this be a vacuum issue??
Im having an Issue with my 95 Explorer Sport. I have Both the P0171-74. Also I don't have heat if my engine isn't running under 3000 Rpm. I've been told numerous causes/Solutions I would like to know your opinion.
iiRobotRock Ok so I imagine the 171 codes have been there fro awhile and the heat problem just started? How does it run at idle what is the coolant level and condition look like?
Hi I have a 1991 Ford Explorer 2 door sport and on the valve cover there is a sticker showing the engin code number, unfortunately the sticker is very badly worn and I cannot find the engine number anywhere. Is it possible its stamped on the engine block somewhere, many tks ,,
Lmao they don’t make ‘em anymore and Amazon doesn’t sell them. Just called Ford and it sells for $160 for the whole assembly. Found the rubber elbow at Napa for $30. This video helped a lot. Thanks dude.
Well, You saved my ass again! 4 years ago I followed the 4 part video of timing chains in my 1998 Explorer 4.0 SOHC motor and its still going strong. Now I went back to your videos because I had the P0171 & P0174 codes. Been working on it for a week. Tried the relearn strategy, Still ran up and down.

I had a rough idle in my 2003 Explorer. One of my best friends, who is a certified Ford mechanic, pulled the codes and insisted that it had a cracked intake manifold. After checking the video, I located the rubber elbow and sure enough.. It was the exact same split. Since it was a Sunday and I am 2 hrs from a parts store... I cut a piece of washing machine hose and Voila!!!! Fixed!!! I then disconnected the battery for 15mins and the Check Engine light reset itself. Thank you very much.. All is good again!!!!
Nice thanks for letting us know!
Can you help me to find the number of the motor on the ford explorer 1993 i cant find this number localization, thanks for yours help
FordTechMakuloco i have a 96 4.0 acting the same way but im not finding it on the side you are in the vid is there a different set up also? I found something similar on the other side
Thank you Todd Picklyk, That was very helpful info, disconnect the battery for 15 minutes and it will clear the check engine light.
i am hearing the air ,why i havent gotten to it yet ,lol. ,reset the code pull neg ground off battery place a piece of cardboard under clamp to insulate from reconnection.using a wire w/alligator clips on both ends touch the ground cable to the hot cable and battery post 5 seconds.only way to erase memory according to one video .good video i havent gotten to the leak truck is gonna be fixed soon i am sure of it now cause i heard real air leak and my idle mostly is problem almost like gurgling
Thank you so much! My 2002 Explorer would not run on its own while idling and found the problem in less than a minute of having the hood up. My elbow was disconnected from the hard tube. Popped it back on and put a hose clamp on it for now. You're the best!

More Explorer vids please. Trying to keep mine on the road it's a 94 Fort Explorer Eddie Bauer 4x4 4.0L it has 312,000 miles I love it and I learned a lot about motors
Is that thing still on the road?? You have the OHV or the Dohc like he does? I got a 97 ford explorer OHV and im at 366xxx km and just replaced the head gasket but now im getting engine too lean codes but im hoping its just my hoses or a broken o2 sensor
OMG. I had gotten a diagnosis of intake manifold leak. I was prepared to just scrap my '03 Sport Trac. YAY! $120 fix from my shop and I'm back in business. THANK YOU!!
I Have this exact problem and been trying to fix it for a few months now. Thanks for the Great video
Did it work my friend?
Changed out the valve gasket on my wife's 2008 Ford Fusion today. Did exactly what you said in your video, felt very confident. The job took me close to an hour. Took my time taking everything apart and cleaning/ inspecting. Waited for about 4 hours for the RTV to cure, then ran the engine to operating temp, found no leaks. Went for test drive and double checked the valve cover for leaks. Wonder how much a mechanic would charge me for this job! Excellent job on your video!
Thank you. I had to clear 4 error codes so my GF's 01 Ford Explorer Sport would pass emissions and I did not notice this cracked tube when I was diagnosing the last two 0171/0174 error codes until I watched your video.
My 2003 Ranger 4.0 never had a rough idle just a sudden CEL for P0171 and P0174 lean codes. I checked my PCV elbows and didn't see any cracks or holes.

+Aztec “Aztecblu” Blue Nice thanks!
Thank you for posting this. I was having a rough idle and noted the P0171 & P0174 lean codes, When I looked at the hose, I was surprised to see that it looks almost identical to your cracked hose. You have saved me some major headaches. Thank you.
I miss my OHV 4.0. 174,000 miles and still didn't have to do any repairs. Still ran like new, ran better than my cousins POS chevy s10 4.3 with 180k. White smoke, crusty oil residue, ran hot even with a good cooling system. Burnt oil too and started getting rod knock.
Better go back and get that 4.0😂
Thank you very much for this info. I have a similar setup on my 2002 Ford Ranger XLT 4.0L. One design I don't like is how the PCV has to be mounted to at port at the end of the Left Valve Cover. A Mechanic had cracked that PCV mounting port off the valve cover and it cost me plenty to have that valve cover replaced.
So, for me that PCV can be very costly to changeout, if I have to change the valve cover too. I changed lots of PCV valve, but I don't want to change this one.
Thanks for taking the time to give us this FREE information.
mcnamee30 No problem.
Another reason it could be hunting for idle other then PVC or TPS or IAC on cold starts is the Timing chain tensioners, there are 2 of them an upper and lower..this was my case.
Great tip. I've had my '03 SportTrac since '05....Pretty decent and dependable vehicle. Replaced this a couple of years ago. You're exactly right, from my experience dealing with mine, really just small components fail from regular wear and tear. The most annoying things were the emergency fuel shut off, and that darn t-stat housing (X3), With regular maintenance the hard stuff been held at bay so I've been happy. My wife just bought a '14 Explorer 3.5 V6. We'll be lucky if it's any where near as good of a vehicle.
Your awesome man! You have helped me out countless times! Thanks for sharing the knowledge, it is much obliged.
Thank you for your videos, they are very helpful. Ok,,, 2 things here. 1st, this is slightly different info here. I have a Ford Explorer 1998 4.0, my PCV valve is way in the back of the engine. It took me a while to locate it. It's also very hard to get to it.
Also, Thank you Todd Picklyk, That was very helpful info, disconnect the battery for 15 minutes and it will clear the check engine light.
Great channel, great tip. Thanks so much for the help you are providing to your viewers.
Keep the vids coming
Great channel.
Well done

p0302 2001 ford explorer sport trac
Encountered this exact same problem on my cousin's C5 Corvette. Very similar design, and it collapsed in the same way. Idle was hunting and rough, stalling occasionally. Was hard to find because the intake tube opening is pretty close to the throttle body on those and it masked the sound. Replaced the broken elbow with a scrap length of fuel line I had in the shop as a temporary fix. That was about a year ago. Still running fine that way.
Great video...mine runs great when warm but a pig when gcold...and worse in winter
Love the channel it's already saved me a butt load of money!! I'm not a huge Ford fan but seems I'm always stuck in one😫so this is really helping me out I'm having a code come up for 02 sensor bank 2 that I suspect is a bad cat or 🐈 🐈 🐈 I'm really wanting them deleted but don't want the bad sounding exhaust or codes still looking for a good cat delete video where everything turns out ok!!
Do you think an imperfect valve cover gasket could cause the codes also? I know it needs to be replaced but I’m hoping the codes will go away after I change it.
Thanks so much for making this video. Fixed my problem in 10 minutes (and a trip to the parts store for DORMAN 48011) thanks to you.Subscribed.
Low oil pressue can also cause chain slack and lean codes
I just searched 4.0 Ford got this video solved my problem.
Gracias
I all ready cleaned the PCV .
Tks to you Iwill check the entyre tube.
Can you make one of the diferent SOHC 4.0 motor?? My motor has the other tipe of PCV tubes/lines
Thank you for posting this. I have a 99 explorer sport I'm having some issues with currently
Mine's somewhere between rattle out and just old and decrepit.... Hopefully it's warm enough before work tomorrow to get hunting for the individual cause... I know one is near the power steering and transmission cases, and there's gaurenteed a few other connections from how long it's had this bad fan in there for.... Dang ol previous owners
Thank you for taking the time to make this video. I have a 2001 sport trac with the 4.0, and I have been hunting a idle issue for almost a year. From what I understand there is a job1 and 2 for these engines. And I cannot find this hose on my engine, I do see the plastic hose that goes to the rear of the valve cover, but no rubber hose on the front of the engine. Do you have any idea's for my engine? It runs ok, but sometimes when you put it into gear it will actually die, and start back up again after restarting the engine. I am getting horrible mpg at only 13 mpg, and have been for almost a year. This thing is driving me nuts. I have cleaned everything you can think of, and you could eat off of my engine. I am crazy about maintaining my vehicles so any oil leaks are fixed as soon as found. But this vacuum leak has been evading me. Any help would be greatly appreciated, one last thing the truck is not throwing any codes and never has. Thanks again.
hope you figured it out! are you the original owner?
Did you ever figure it out?
@@SBS_Auto I purchased it with low miles almost 20 years ago now. I did finally figure it out, the problem was the idle control sensor I think it was called. It's right on the top of the intake in the center. Took about 3 minutes to switch out and it's ran perfectly.
@@cassandramoon8797 I did, it was the idle control sensor. It's on the intake right in the center.
How can you not like this ? Ahaha 😂 I fixed my baby with this merci beacoup
Hey Brian, I am most likey off topic here, but I'd like to know how to get a good front end alignment, repair/replace child door locks and headlight alignment. was given 2000 explorer XLT. You could say a rolling dumpster, it was and still is in need of a lot of TLC. Yesterday the engine ran erratically, and died when wife drove to work. She thought it may have been overheated. She added 50/50 mix antifreeze and it appears to be ok. However, after viewing video, I will check that tomorrow. I am unable to drive, and apprehensively must ride in it to Dr.office. It seems squirrly on the road, one slight overcorrection scares me a bit, much like a willis army jeep. Is this because of the wheelbase being short or incorrect tire size? All 4 are the same, just smaller. Thanks for videos, and your time/expertise.
My explorer does the idle up/down surge only in the winter, but not the summers... Would this be the problem? I'm not near it right now so I can't check it... but I was told it was the IAC also. Before I get parts and drive to it could you reply?
Our '06 Explorer runs fine, but the CEL just came on. 2 weeks ago, the MAP sensor was replaced for a different code and now this popped up yesterday.
Thanks Brian your a good man!
I'll give mine a look. I have been finding a leak here, and a leak there. Its insane.
Have you ever replaced the fuel rail pressure sensor on this particular vehicle-in the video? I'm trying locate the sensor on my 2003 Sport Trac (4.0 OHV) but I can't find any videos covering my model year(2003). Any help is greatly appreciated---thanks.
I recently bought a 96 explorer. It appears as though I either don't have the same elbow or I am struggling to find it. My engine scavenges at warm idle and I believe I hear a faint hissing, it also is throwing a P0133 code. Tried spraying carb cleaner around the entire intake manifold and vacuum lines and didn't detect any change in idle. Any help or ideas would be great! Thanks.
It would of been nice to actually watch you replace it, you say easy to just fish it out but I would like to see and where it goes it back, best way to get to that PCV valve and show to replace the valve, cant find 1 video...PLEASE post one if you could, definitely be much appreciated!! Thanks
I have an 2001 ford explorer sport track 4.0 v6 I have replaced maf, idle control. It sits at idle then dies, check engine light on. I went and had it checked it said running to rich.
You're the man thank you for this tip awesome channel love it and subscribed
i spent hundreds of dollars on lucas high milage. additives. oil stablizers. car runs silentlike a prius. and its as 2003 ford explorer with 226k miles with a new tranny new radiator new water pump new starter new spark plugs new bAttery. welded exhaust . new tires brakes rotors calipers and oil changes at 2500k ....
Great Video I have a 2000 Ford ranger 4.0 with it showing a P0171 lean condition bank one Check Lite... once every 300 or 600 miles .. The truck is running good... only one time it would not idle . Could it be a Fuel Pump going bad? Over all the truck is running great .
gotta 98 ranger 4.0 been babied and is mint 100k miles, I just started getting 171 174, checked pcv valve hose fine, I smoke tested , sprayed brake clean, and tried propane when cold and warm and no change to engine speed but short and long trim stay in 25% range when I take it and and give it gas long term dives to zero. Fuel pressure 65psi, new fuel filter
I dont want to change intake gaskets Unless I have sure reason to. Or is that the only option for vacuum leak in this engine, Maf reads fine, and so do O2 sensors, no exhaust leaks, what would you try next.Your the best on the net!
Assume! Nailed it! My 03 Ranger XLT suddenly started running rough, nearly dying while idling and unable to rev over 2000 will accelerating. Seemed like it was running out of gas; it was not. Then started running better after. No check engine lite and no codes. Change fuel filter, checked fuel pump related fuses and relay. Everything OK. Just drive it. Now, two weeks later, it throws two codes: P0171 and P0174, right and left banks lean. The Chilton manual is pretty much useless for this so did a google search for Ranger P0174 P0171. Bingo! The first hit was not quite right so checking the other hits lead me to your video. Great video and thanks for the tips.
Hi. I have a 2000 Mercury mountianeer 4.0 soho engine. I have a pretty rough idle. No DTCs. Fuel trims are ok, long term is adding a little more than normal. I checked my pcv and it's not leaking. My PCv is in a different location than this video though. Any thing common with these? Sort of hunts. Only rough at idle. Minor contribution hits on most cylinders.
for the 99 explorer 4.0 ohv is it just a hose from the intake to the pcv valve i have the codes p0171/p0174
I haven’t got my codes checked but I have a 95 explorer and I believe it is the same problem I changed the spark plugs and still was running funny so I’m hoping it is a vacuum leak
great easy explanation of this repair... Question.. I have a 01 explorer 4.o sohc and I am getting a jumping tach needle. I can not find anyone who has a answer for it.. it will sit at idle then start bouncing around... Any clues?
I just subscribed I have a 1998 ford ranger 4.0 liter v6 xlt 4x4 I got the p0171 p0174 codes could I have the same problem as in this video I have rough idle
Did you solve your problem? I have same truck same problem.
I have a 02 f150 5.4l sohc wont rev over 2000 rpm when at full operating temp just put in new plugs injectors and coils I removed cats and still doing it fuel pump and fuel filter brand new also
Could be injectors
love the videos bud! I work for a ford dealer up here in canada. how does your work place like you making videos?
They don't mind at all actually.
Good man.. I love your videos.. Keep up the good work..
If my 1998 Explorer sits up for a few days when i need to repair it, I'll start it and get a strong exhaust smell coming out of the front of the engine that kind of dies down after a few days, but not all the way, and before it sits up I smell burning metal from the front !!
Mines too
had a similar problem with my mercury mountaineer (basically same SUV as these explorer, just a luxury version)
Thanks for the information. Great video
I have a 2002 Explorer with the same problem. I bought the PCV elbow tube {Motorcraft KCV190}. The other problem I am having is, I can't seem to located where it goes.
I've a,94 explorer xlt.4.0
I'm having issues with my rpms going up. Then down. It's starts very good.
I've been told the power brake booster could be the culprit but darn like you said. All these parts can't just go out I'm not ready to sink much more..
Any suggestions
laschell59 If you truly have a large vac leak like I think you do then you can just take off each vac line and plug the port to see if the problem goes away.
FordTechMakuloco i changed the throttle postion sensor now my 20p5 for explorer 4.6 wont stay om it dies right away
I just did a top end job on my '99 Explorer 4.0L SOHC (heads replaced, every gasket and o-ring, timing cassettes, tensioners, chains and sprockets, etc.) and now my brake booster is leaking vacuum. It's running rough at idle, but no codes. Whenever I disconnect the line running to the booster and put my finger over it, the engine continues to run rough. I did have 90 psi compression on #1 cylinder, but I believe it was a stuck ring. Compression is now around 150+, so I know it isn't that. I haven't checked the PCV yet, so I'm going to give that a shot next.
Any tips on what else can be causing that?
Thank you Brian, With 2003 Sport Trac V6 4.0L what must I do to re-tune or adapt for flex-fuel...?? By "flex fuel" I mean using any combination of Gasoline, E10, E15, E30, E50, E85, or pure straight ethanol....{in a just pump and go fashion}.
Since or local stations now put in random amount of ethanol I never really know what I am running.. E85 might be E50 .. Pure Gasoline does not really exist at most stations in Missouri {due to government mandate to add ethanol/alcohol}.
So I just got my check engine light for these codes on last night. And this morning I was looking around my engine and I realized the part that you showed me that had the hole in it was actually just disconnected from the tube so I reconnected it but my engine light still on?
When I startup my 1995 ford explorer it over idles like it idles almost to 2000 rpms and then it would go down and when I drive it over idles to what could be the problem?
what about on the later model with the electronic throttle?
Looking for that video on how to reset the pcm to relearn memory, thanks
I have a 2008 ford ranger 4.0. , I'm replacing spark plugs with motorcraft plugs that originally were in. Is it recommended to provide anti seize compound on the plugs , if so what brand ?
Will you make a catalytic converter video?
My fiance 99 exsplorer 4.0 has been fixed twice and still runs rough so any suggestions if I check the tube and it's not that. I've worked on cars years ago but not these often. I'll check the line soon and hope it's this since she's paid the guy over 300 already once a tune up and today 200
Hey I have a 1999 ford explorer 4.0 / 2 wheel drive the oil gage started bouncing around today and 30 min later it started a knocking noise I changed the sensor already and it's still doing it.. The knocking makes me think it's the oil pump can you tell me your thoughts on this and if you think it's the oil pump what's the easiest way to change the oil pump??? Thanks in advance
Aaron Stoner if it started knocking then an oil pressure test is in order if it its low you need to look at the oil pump drive under the cam synchronizer first then go after the oil pump. How is the oil level?
FordTechMakuloco I Drive a 1997 Lexus es300 I change the mass air flow sensor the PCV valve to Idle Air Control i change coils & the spark plug and everytime I go over 80 miles an hour the car. Rpm idle pooly whan i come to a stop
Where's the link to resting your PCM figured? You mentioned it be posted in the video description, only see part links : (
hey this video helped me with a start to my problems. I have a 2001 ford explorer sport Im also throwing codes p0125, p01121 im having a hard time with these can you help!?
Hey! Good evening. I have a 2002 explorer 4.0 with a new engine with no more than 4K miles on it and my rear timing chain has a bit of a noise, I’m wondering if I can get away with replacing that external tensioner. Not sure why my new engine would have any noises at such low miles.
hi you helped me out before i have an used 2005 ford 500 limited and never changed the wipers before one was have gone went to change the wipers at advance auto and the guy told me he aint never seen a nut on each one to hold it on and said i might have to replace the wiper arm and i want to know do i have to changed the wiper arms to get the right end pieces to lock the wiper blades in instead if the silver nut please help have pictures and don't know how to post pictures on here
It seems the arm has been botched yes, all wipers clip into the arms no nuts or bolts required. I would change the arms out and some new blades and you will be all set with the correct arms and tension so you have good clearing of the windshield for the upcoming fall rainy season and winter snow.
FordTechMakuloco
thank you always been helpful and i can get them thru advance auto or fordparts
Why does ford have two different style Upper Intake manifolds for the SOHC for these model years. Like mine is two huge double barrel things and this one looks like what most rangers have. My last explorer which was a 2000 XLT is same as my 2001 Explorer 2 door Sport which has same front end as a Sport Trac because for some reason they couldn't decide on that either.
Mark Wolf is your pcv tube in a different spot?
Mark Wolf they have an ohv engine which is better than the ohc engine
I thot some of the readers might want to know, if you happen to accidentally switch plug wires 5 and 6, you will get a P0174, high long and short term fuel trim bank2 only, and loss of power, but no check engine light, and no backfires, runs only a little rough,, ask me how I know :) the correct cylinders are noted on top of the coil , very faint on this vehicle but i was able to find them
I have the exact size motor in my Explorer, but its 2000 model. My oil pressure gauge is going haywire and there is some ticking in the motor. I love my truck. So I parked it. Do I need to just replace it..or is there a not too expensive resolution...??
can you find this leak if you spray carb cleaner .. wouldn't the make it change how it runs
Great video, i got a ranger 4.0 and in park it won't rev over 3000 rpm, is that normal?
Thanks López.
Hi I have 2006 Mercury Mountaineer, recently I am facing a problem with shifting of gears, loose /free shifting, and not engaging to the selected gear, some times gets engaged after a minute. Power train malfunction indicator shown in instrument cluster. could you suggest the real cause of this issue and how we can tackle it. thanks in advance.
I have a, 07 explorer, 4X4, 4.0L with just over 80,000 miles, that runs rough idle and dies after I have driven her for a while gotten her up to running temperature and shut her off, resting for 2 - 30 minutes and then try to restart her. I have changed my throttle body, MAF, intake manifold gaskets, (caused they leaked) and still have the same issue. Codes come up with a p1000, but that is no big deal, and had a B1676 error pop up, but I do not know if that has anything to do with the engine running rough, I have no idea. The only thing I can think of after this is spark and fuel. According to my scanner my fuel is now with in normal range, which leaves spark. I was thinking about changing out my ignition system, Spark plug wires and spark plugs.
What do you think.
need your help. what is the piece called. on a 2004 Ford explorer. not the radiator but behind it. there are 2 hoses that connect to it. right above the drain plug of radiator. It's the one right behind the radiator, thank you.
I have a 2008 Mercury Mountaineer and I just replaced the thermostat housing and the intake manifold gaskets. Now that it is all back together it I am having a very rough idle/misfire. I took the intake back off to investigate and there is now oil in my intake at one of my cylinders. Could this oil be caused by a manifold leak, which would be causing the misfire/very rough idle? Tricks on getting the intake manifold to seat well? thank you
I have a 1999 ford explorer sport, does its spudders when you make a complete stop it will spudder here and there like it wants to turn of but doesn't the idle barely moves when it spudders , put it in park a leave it for a while like a minute and it tuns off byitself?
Thanks for all your helpful videos! I have a 2000 Explorer Eddie Bauer 4.0 SOHC would this be the same design and replacement part as the sport track? I clicked on your ebay link and it claims the elbow fits my vehicle but I just wanted to double check. Wasnt sure if the design was different in the prior gen 4.0 SOHC. Thank you again!
Richard Gawronski Yeah all the engines are the same so it should work.
Really enjoying your videos. Ive got a 2006 4.0 explorer with rough idle as well as when cruising at around 1400 to 1700 rpm the engine feels like it misses which is an annoying uneven ride and no problems when foot down on the gas. Could this be a vacuum issue??
Paul Seaman No once your at speed the vacuum leaks are null you have a secondary ignition fault causing the misfire.
Would this issue create an oil leak if left unchecked?
Im having an Issue with my 95 Explorer Sport. I have Both the P0171-74. Also I don't have heat if my engine isn't running under 3000 Rpm. I've been told numerous causes/Solutions I would like to know your opinion.
iiRobotRock Ok so I imagine the 171 codes have been there fro awhile and the heat problem just started? How does it run at idle what is the coolant level and condition look like?
I have a 94 ford ranger rough idle problem replaced fuel pump filter and Pcv valve same issue Any suggestion on it new plug and wires also
This exactly wat I fixed on my 03 but it’s still idling rough, any thoughts?
Great video. What's the part number on the PCV tube?
***** Motorcraft Part Number KCV-190
What is the measurement of the boogie cap gap? Ford Mountaineer 2007
Brian do you have any explorer 4.0l v6 timing chain replacement video invoking removal of the engine to get to the rear cassette?
Hi I have a 1991 Ford Explorer 2 door sport and on the valve cover there is a sticker showing the engin code number, unfortunately the sticker is very badly worn and I cannot find the engine number anywhere. Is it possible its stamped on the engine block somewhere, many tks ,,
