FordTechMakuloco CARB legal?
Great point Geek. You can buy cheap parts all day. Do they work properly, do they work within the parameters that is called for?
+GeekDIYMechanic Magnaflow offer CARB approved options in most instances.
+Richard Ostrowski Magnaflow is definitely the premium aftermarket option here. In most situations they offer an OE grade cat option with longer warranties.
FordTechMakoLoco what method do you recommend for removing the cat assemblies from the manifolds without breaking the manifold studs?
A good idea is to take your scan tool and connect it to all your vehicles when they are running perfectly and then record all the normal waveforms and values and then save them. Then if you have a problem down the road you can compare the current abnormal waveforms and readings with the normal ones from before. This will often make a problem obvious during troubleshooting. I have a full set of normal readings and graphs recorded for all my vehicles to compare with if a problem ever comes up.
That's a great idea. I was thinking the exact same thing. Just have to have good readings first. Not there yet.
If could meet this guy I'd have him sign my dash
Same
I would buy the dash
😂😂
OMG I had this exact same problem. The Garage took me for a fool and changed all my plugs, coils. It still hurts to sit down.
Another awesome video. I'm a ford technician and I've been watching your videos for a couple years now. Keep it up they are so helpful!!!
Dude my guy, this is been a issue for me for 3 years!! Changed every sensor, timing redone, exhaust system redone new intake.... I have the same readings as your video. Bank 2 for sure has a clogged catalytic converter. THANK YOU!
Just had my cats replaced on my 2009 F250 5.4 3v. #5 exhaust roller follower was seized and replaced. The engine started to tick. The reason it went in in the first place after seeing your vids on the 5.4. Fortunately caught it early and no damage was done to the engine. You saved another 5.4 out in the field with your advice. Mine! Thanks Brian.
Good video, I like that you showed the before and after readings and explained everything in detail as you were diagnosing the problem. Then interpreted the readings so we could understand what was happening and what good o2's should read.
Thanks for the help . I just passed my California smog check after replacing the cats on both sides and the muffler as well as addressing a head gasket leak .Not only did it pass but the numbers were a fraction of the allowable limits on all three types of emissions !
Turning wrenches is the easy part of working on vehicles diagnostics is the hard part. And you’re a beast at it. Thanks for the videos. 💯💪
Been building cars for 20 years. And I don't touch my F150 until I consult Ford TechMakuloco
I know that this video is kinda old at the time I am writing this but I thought that this was worth commenting. I have the exact same year and model as the F-150 in this video with the same engine and the same problems. This video helped me to diagnose the issues that my truck was having. You did an excellent job teaching why this happens and the rest of your videos are amazing as well. Keep up the great work @FordTechMakuloco!
You are the best. I am having very similar issues with an 05 Taurus OHV. Plus i get random misfires. Sure thinking CAT now.
You're the best tech I've seen on tube.fords finest tech
Very nice video, simple but very instructive. Learned a lot from it. Keep up the good work.
Great detailed instructions. I have a 1998 Ford F-150 . Was doing the same thing. With my travels I do go through different sea levels. Problem was my trucks catalytic converter. Great information. Thanks.
Wow this was a “tailor made” video that I have with my F150 truck. Mode 6 was detecting mis fires #5 and yes a destroyed cat just like this video. Hope the new cat will play out the same.
Cool diag, Brian! I enjoyed the whiteboard explanation segment. The scanner can definitely tell you a lot right from the driver's seat. Personally I still like to back up the scan data with a backpressure reading at the upstream O2 locations. Only takes a minute...if the O2 sensors don't fight you that is lol
That is the problem many times on these engines they gall up in there and you end up pulling the threads out with them. I have never found this diagnostic method to fail me but I do have a manual gauge just in case things don't add up.
I just update the exhauspipes with testing ports that you can plug and unplug when needed.
That way your ECM/PCM can still use o2s and you can be sure you dont brake them in testing backpresures.
Allso dont forget that muflers can allso be pluged...
If you heat them with a torch you won't pull threads
Glad I subscribed! I have changed MAF sensor, PCV Line and Front O2 Sensors! Truth be told I think I want to replace the entire exhaust.
sir, your scanner is at the top of the line, and you as well; keep up the good work.
I was waiting long time for this video! Sorted all b4 anyways. Thanks a lot Bryan. Keep the good work and these great videos!!!
Great video and love the expanded explanation of what is going on. What would happen (hypothetically) if you installed a straight pipe to replace the bad Cat and didn't use the downstream O2 sensor?
I am mechanic in puerto vallarta mexico thanks for another great video my frend pid baro is a god diagnostic.
Man I enjoyed it, learned a couple things I still didn't know.
Thanks for another great video my friend. I learned so much from this video. I am not a mechanic but I am so interested in this stuff.
Thanks for the video you saved me money and headaches.
I have a 2005 5.4 Triton. Certain I have this issue. 187k miles. Debating new Engine from Dealership, ( my cousin is the GM, I get a good price) or just replacing everything i.e. Phasers, oil pump, tensioners, chains, rockers and lifters . Those are the only parts i have Not changed out yet. It ticks, idles poorly until warmed up for 15 minutes, throws a 0307. Love the truck, wish I had the 5.0 Thank you for your help. I have been able to enjoy working on my truck with your expert advice. Thank you for telling me about the Amazon deals too! I never would have known.
Have one in the shop now and it's been a headache. Thanks for the vid!
Sometimes I think what Doesn't this guy know. Always amazing and well detailed videos. : ) Was this also common for the 4.6V8 2v?
good video brian..can always take non contact thermometer and check temps in and out of the converter.. even those cheap $20 harbor freight ones work decent.
What should temps read?
Omg thank you! I was abt to start to replacing spark plugs. Wires. Egr. Etc. never woulda thought abt converter. Def the problem. Barely any exhaust coming out of pipe.
I’m about to look into that on my 04 f150. Very useful information. Thank you.
Great video and very informative. I've watched all your videos on the subject because I currently have the old P0430 on my 2011 EcoBoost. I have a new driver side cat coming in, so I was curious, what is the swap out procedure? Would you consider making a video showing your method? I'm sure it would help a lot of folks out.
Thanks for sharing your skills, of course that it'll help me next time in my work to make a good diagnostic on the cat converters you got my like keep the same way posting good videos and im a new happy subscribers
Brian my compliments to you on very well put together presentations with a wealth of information for us f150 drivers in particular.
I seen @ video you did a while back on resetting the pcm by disconnecting the negative & then using mini jump cable to drain the capacitors ??..I'd that a procedure you still recommend doing if my truck is showing shift issues??..It'd a 2008 f150 5.4..Thank you.
Excellent video, great job explaining how the scanner results led you to your diagnosis!
That's crazy. At 71,000 miles. I have the exact same 5.4 3V engine at 348,000 miles, and it runs like a top. Only ever changed the starter, and both VCT solenoids because that seemed like the flavor of the day, so I did it. Yesterday I replaced all SP515 spark plugs to the new SP 546, and I cleaned the throttle body completely. Runs like my wife's Ford 2.7 Ecoboost. I'd put a straight pipe in place of the catalytic converter and be done with it.
Dude, I swear you're a wizard under a hood. I wish you were a cousin of mine so I could get you to work on my truck for free. LOL
pfcjking1 not for free, obviously give them at least something back
Doyle would whip the tar outta me... mmm hmmm.
HAHA
FREE? nothing in life is free, quit being so self entitled.
@@tttarms1970 if you only knew how much "horse trading" goes on with my family. It's not free, by no means, but no money gets exchanged. If you're an electrician, you'll get a call when it's time to pay up for that "free" help.
Reminds me of the vid you put out 2 years ago Jun 4th 2015, Same kind of issue. Cat was plugged up on that '07 Expedition 5.4L
Yeah that was the first stop on the summer tour.
I believe the reason #5 misfires is because it fires right after #6, the rest of the cylinders on bank 2 fire after bank 1 giving time for the pressure to drop in #2 manifold.
The best method I've found for finding/confirming a clogged cat is temperature. The outlet on a working cat should be hotter than the inlet, if it's clogged it'll be colder. A quick scan with an IR gun will tell the story.
My 2010 F150 5.4, melted its cats on the way back from Florida, a couple years after I bought it, it was still under warranty. I could hear the difference.
Did you all of a sudden lose power ...and did you have any miss fires ?
Did gas mileage drop
Exact problem with my 2006 King Ranch . No power, no acceleration, misfire on Cyl 5, and even rough idle. I can hear the rattling in the Cat while driving. Thank you for a well communicated video
I got a new magnoflow setup Cal all the way front to back new o2 sensors aall at 290K orig motor, never been cracked open.
Lits of good info... thank you very much!
You are the ford man.
I have an 2006 Expedition, EB package, 127k miles. Been having some issues lately and this explanation has helped me understand more. Two weeks ago Autozone read a code that Bank 1 sensor 1 was rich, replaced sensor drove interstate and ran good. Parked for 1 1/2 days and CEL came on again, This time it was reading bank 1 sensor 1 rich and bank 2 sensor 1 lean. I will be looking at it tonight with a mechanic friend. I'm also thinking vacuum lines or MAF. The last two winters have been cold and a field mouse has built nest behind MAF a few times. One vacuum line replaced last year. Another appears to be dry rotting, Replacing vacuum line tonight.
you're the man thanks for the info
Another great video that's easy to follow! Thank you! Also, is there anything you recommend to help keep the catalytic converters clean for the life of the vehicle? Clean oil, fuel system cleaner, avoid too many short trips, anything else?
Prevent oil consumption, adding a catchcan to keep crankcase vapors that contain engine oil from being burned and sent through the exhaust, avoid running lean as that can make them melt down.
Been a fan going on 3 years now. I had a misfire on the number 5 and Change the plug, coil and still had an issue at that cylinder. So I get on the freeway and couldn't get over 40 miles an hour going up hill. It did increase going down here. I kept an eye on the RPM and it had me thinking something was wrong with the trans. I had never had problem with it. I got a new engine put in and had them service the trans. So since I did a crappy job, and lied about the service they was going to give me on the engine, I was thinking another thing they beat me out of my money on. So I start watching your video one after another. They shop said it was my intake. I was like it runs and sounds great at low speed. So I did not listen to him. So when I first got the truck 6 years ago. I used to get cat lights on it. But when I drive from Minnesota to Mississippi that check engine light never comes on. But this time it end up being the cat. Another shop told me that changing the cat will not solve my problem. I made a bet with him. He didn't go for it. I am happy to say that my baby running excellent right now with the CAT change Thanks to you sir. You are the best sir. My baby got up to 115 yesterday. Now to get rid of this and never buy another Ford unless it have a 351 in it. Never every had a problem with my Bronco. Should have kept it. Traded it in for this truck.
Yes very well done . Thanks I have an 2004 lincoln Town car 4.6 it has a tremble in drive with foot on the brake, other then that runs and feels great. new tue up etc. dirty intake ?? Thanks agian
Excellent video and phenomenal diagnostic skills! My question however is wouldn’t the 02 sensor detect the plugged cat and throw a “Catalytic efficiency below threshold” type of thing????
+Bill Williamson not until it totally fails and the rear matches the front all the time
Very good info. It backs up my techs diagnosis. I have a 2008 f250. Bought used from private owner. One concern of mine is why would my gas gauge fluctuate? From a full tank in drops to half in less than 50 miles. Then fills up on 9 gallons. It’s a 30 gallon tank. Do I need a new fuel pump also?
Do I replace both catalytic converters even tho one is the problem?
Thank you, for the class
Wow timing problems at under 80k......glad it waited till 150k for me.........thanks again Brian!
Cool stuff - Wish I had that scantool...
This was an excellent video. I finally had to buy a replacement cat for my 06 Impala SS because I have the P0420 code and check engine light on. I’m just worried now that I won’t be able to get the bolts loose where the pipe connects to the manifold. Any suggestions? I anticipate the others to break from so much rust and that’s ok, but those other ones intimidate me..
Really enjoyed that one. Great info on the rear o2 should flatline. And the baro info excellent. Thank u Brian!!
Wow man I have a 1981 5.0 motor in a 1981 F-150 Pick up truck and the exhaust is overheating the starter I bet it has the same problem the cat is probably plugged up thanks man I’m going to check that out.
Bro I have the same problem lost power but I have no codes even I put cold intake for more air and no improvement I check the catalytic and seems in good condition a mechanic checked and say that everything is working good I haven't find a good master like you. I will keep watching your videos to figure out what is the problem
I’ve got a 04 f150 3v that 3 Ford dealers couldn’t figure out. It runs great , no misses but will not rev . Every so often when taking off it will get the burst of power you expect back goes right away. One Ford dealer said it wasn’t advancing timing. Not sure if it’s timing or vct. My truck looks new and has low miles 137.000 but is mostly worthless. I wish I was close to you. My other 3 V engines are awesome cam phaser lock outs and a sct tune.
Excellent teacher
I really like your videos! I have a 4.6v and a 5.4 v, run 5w30 ,
I have an 07 5.4 and I know there's problems even though I've had the mechanic scan tool. There's no codes showing but I get the sulfur smell and no power. I know one of these cats got to be plugged up but nobody figured out which one yet. 8 miles to the gallon. Signed fix or repair daily
Great video! What diagnostic tool are you using?
Could a dirty MAF cause low BARO readings too? It could also give you lean codes without throwing a MAF code. The tell tale sign in this case was the long term fuel trims showing lean on both banks but worse on one than the other, pointing only towards a plugged converter. Not much else it could be on this design. Thanks for video.
Niice job with the repair and video
Do different vehicles equiped with baro sensors operate at similar frequencies, or is this manufacture/engine specific?
You would think they would make it toss a code when the converter flow stops?
Nice fix Brian. Gotta admit though, I'm not exactly clear on why the clogged cat affected the baro value. You probably explained it well enough, I'll just have to watch again. Thanks!
+Baxrok2 the whiteboard part is where I explain what is happening.
It has to do with the amount of flow thru the engine. If the exhaust is restricted due to the cat being plugged, it affects the ability of the engine to move intake air. The maf constantly monitors this and uses the data to extrapolate fuel mixtures. If it can't breathe right, it won't run right. It is akin to being in a high altitude area with thinner air, like driving in the mountains with a naturally aspirated( non turbo or supercharged) engine. More throttle input required to get any power.
Also could use a IR temperature sensor measuring before and after each exhaust pipe connection.
That is another method to check if the chemical reaction is taking place yes but I have found that to be unreliable and would only use it to back up my scan tool findings.
The best way to evaluate cat efficiency is to look at the upstream and downstream waveforms and compare them. The upstream one should be varying and the downstream one should be relatively flat. Comparing the two waveforms is essentially how the PCM continuously tests the cats and decides whether to generate a trouble code and turn on the check engine light.
Fantastic video, sir!!!
I did a 2006 with a cylinder 5 misfire today and 02 sensor looked the same baro was at 146 and no cat codes the shop replaced coil and plug and then called me I did back pressure test and verified it now that I watched this video I'm sure off it now brain is very good I watch him scanner saner and Eric thanks brain
First off I really appreciate your videos and hands on information. Saved me a lot of money and I gained a lot of knowledge. Ok so along with the new startup rattle, this is part of the current problems on my 2006 5.4L F150 Fx4 due to age.These 5.4L definitely have a story to tell I just want to know if mine can have happy ending? Thank the internet for good deals on Parts and review research and price checking, it's pretty afFORDable lmao. So I just wanted some opinions? If I buy the timing kit with cam phasers, crank bolt,chains,etc(+ crank timing set tool and rocker roller removal tool) the updated oil pump(+5w30) that you suggested from the Mustang as well the cam phaser and O2 sensors And replace my whole exhaust catalytic converter you think that should bring my Ford back to normal if there's no major issues that come up?I've driven literally across the country and back, beaches and lakes countless times plus my daily driver. The way I see it if I do these repairs I'll be $15000 dollars TOTAL into my truck and a couple weekends in the garage. But Feedback and suggestions are appreciated.215000 miles at the moment. Bought it early 2016 for $9000 at 145,000 miles and overall a great daily driving truck just been loosing it's balls lately. I've done most labor on it except for trans rebuilt.put about $4500 total since I bought it through time. Mainly for repair and some performance. A rebuilt transmission(repaired at 175000 miles),all new suspension, Rancho lift 2.5",arms and ball joints, rack and pinion, power steering pump, alternator, battery, VCT solenoids,4x4actuators+hose and also my yearly tune-ups coils and Sparks and oil changes.There is no turning back now hahaha.
2003 ford Taurus 3.0 miss fire on 4 5 6 , plugs are good, fuel rail good, coil pack good, was told possible cat clog or cam timing..... what's your take on this. Thanks
Brian,do you have any vids on Ford truck rear ends?ring and pinion setup,clutch pack replacement,3 pinion v/s 2 pinion LSD v/s torsen,pros and cons?
I have a 2009 5.4 3V F150 with 90,000 miles. I have just no power at low rpms when going up hills and any other high demand acceleration. I replaced all plugs, coils, and even changed the MAF with a new one. Started doing this only a month or so ago. Not throwing any codes. Seems to be a little more pull once I actually let off the gas when the RPMS are high. Ive also used your technique to reset the computer by unplugging the battery and connecting the negative cable to positive battery terminal. Really need some help! Thanks
I found out this was my problem wish I had seen this before I did all the other things was about to replace my engine found out yesterday catalytic converter was clogged.
What symptoms did you have
Great information
the best info for ford vehicles
Just bought my first Ford truck and it's having a problem with power going uphill at 60 miles an hour it runs fine around town but it has an issue with power loss on any long drive.
2004 f150 3v 5.4
Hello I enjoy your videos I'm wondering if you can help me out on my problem I have a 06 Ford Explorer 4.0 I have a constant ticking it's not the exhaust gaskets it's always there sometimes it's more pronounced than others I've replaced the lifters but still have the taking very annoying car runs very well very smooth
My baro reading is 149Hz but it seems to be stuck at that number even if I clear codes key on engine off.. Bank two is super lean according to my fuel trim readings. All cylinders miss firing. I haven’t smoked test the intake because I’m at home doing the side job. I’m suspecting a plugged catalytic converter
Of topic question, I have a 05 5.4 and my battery light came on with a p0622. So I installed a bigger battery and a 130 amp alternator. All the grounds are good but it is running at 12.8 at idle. What else should I look for?
What are some common transmisson issues with 99 f150 with the 4.6 triton
hey I have 2011 ford mustang it has a engine knock but not at idl it's starts when you accelerate or rev the engine. i think it's possibly the timing phaseres. What's your thoughts on it
Very good video, thanks.
Did that clear up the other codes? Does running cheap discount gas (non top tier gas) clog the cat in time? This ethanol gas is crap! Thanks for the vid!
I'm having a 02 sensor code, changed all 4 plus I flushed Antifreeze and replaced temp sensor. 2006 f250 5.4 a plug cat for sure
You mentioned you are in Chicago, where about in Chicagiland?
I would love for you to work on my truck. No one else can figure out the issues with it. Very similar to what's going on with the truck in this video.
Thanks!
Looks good to me. Mine is a 95 ODB1 4.9 inline six with 1(one) o2 sensor so I can't get multiple readings...
I need a mechanic like you all the mechanics i have experienced are sketchy and have minimal diagnostic skills
They don't make money by doing logical diagnostics. They make money by replacing parts and charging you until they guess right.
isnt it true,hard to find anybody anymore that can actually troubleshoot anything,their answer is just replace the whole thing,went to a tranny shop the other day,all i wanted was them to put a clutch pack in a carrier case,already had it out,just couldnt find a tool to take the spider gears out,had everything i needed to complete it,they weren't interested,not enough money in it,their answer was get a new carrier,ring and pinion and they would put it in for me for $700,really,and forget about the old days when the guys at the parts store actually had worked or still did as mechanics and knew what you were talking about,now its some kid or a retired walmart worker that just punches keys,wtf,like talking to a zombie
I've got a 2006 Ford Expedition Eddie Bauer with the 3v 5.4 Triton motor. I've replaced the plugs twice, the cam phasers, the oil pump, the coil packs in the 5 years I've had it. Recently I've began experiencing low power having to floor it and get it over 3500rpm to get it to get up to speed on an on ramp or to pass a slow moving vehicle. I ran the crap out of it for about 15 minutes using over a 1/4 tank of gas and stopped looked underneath and both cats were glowing orange, and when you run it with the windows down you can hear pre detonation and what sounds like a bad exhaust leak. I parked it and just waiting on some time to pull the manifolds and y pipe and weld in some test pipes in place of the cats to eliminate the problem. Can I disable the post cat 02's so the CEL doesn't stay on all the time? This is the first Ford I've done extensive work on, I've done 5 LSx style motors, and back in the early 2000's installing headers and eliminating the downstream O2 using HP tuners.
Hey are you going to AutoMechanika would be great to meet you there. Good video as always
+Techman 48917 I was going to go but I am overloaded with work right now.
I just ordered some hi-flow (200 cell) cats for my 08 F150, but the new cats do not have the O2 bung in them. Should I just install bungs just behind the cat in the regular 2.5" piping for the O2 sensors?
I just installed a OBX header and cat system in to my 2006 Ford F-150 5.4 and getting a po420 and po430 can you point out what would cause this?
Does the check engine light always come on if you have a plugged catalytic converter
My 11 ecoboost f150 popped the 430. Dealer is replacing the bank 2 cat and re flashing the pcm. They gave no reason for the cat to fail, so in your best opinion, what causes the cats to fail and what can be done to remedy it so it does not happen for awhile?
Need you in my town!
Wow...I thought the barometer reading was a raw sensor...Very interesting to know it is the result of an algorithm based on other actual components(MAF/RPM)...I never thought to look at the reported value as a diagnostic point of reference..
beyond a bad 'baro' sensor - which, I find from you, doesn't exist! It's probably true for most cars...
Very freakin' nice...Thanks...
Only in rare instances has Ford put a stand alone BARO sensor on the vehicles and when they do it's inside the PCM.
2006 Ford f150 5.4 2wd here. Would the beginning stages of this cause a rough idle???? No codes. All spark plugs and coils new. New vct solenoids. Thank you
