- čas přidán 29. 08. 2024
- In this video I have a look at a 2004 Chevrolet 1500 that has had the parts cannon unloaded on it! Injectors, MAF, MAP, fuel pump, plugs, wires, you name it they changed it! Now we need to find out what the real causes are for the negative fuel trims and rich codes. Put down the parts cannon and follow the facts folks. -Enjoy!

Now we wonder... did you get paid!? 😂
Mike is great.
As usual, great job!!!! Love watching your videos.
@@OneWayWillie you’re an interesting human.
I hope the guy payed and thanked you!
SMA; you have said that you're not the greatest mechanic. We appreciate just how humble you are. But we your subscribers feel that you are a GREAT mechanic! Keep up the good work and take care of yourself and your wonderful family. Peace.
Spot on, he doesn't realize how good he is apparently.......he hangs with some top notch talent though......no matter how good a guy is he has a guy he calls when he's stuck.....having to call once in a while humbles ya.....Eric's easily a better tech/diagnostician than anyone I've met in my life....he combines it with an amazing teaching ability.....amazing talent
Well, to be honest alot of the guys up here in niagara county, newyork at the napa and advanced auto shop classes. Said Eric.O is a legend in their books. They want him to teach classes.
I've seen better mechanics... But not many. Just kidding, Eric is damn good.
100% agree. Also he let's us know if he can do it so can we but I have plenty of extra money receipts from not being able to do it without triale and error. He is one of the best.
To be fair if Eric lived in my town he would be the best mechanic by a clear margin. He's probably in the top 20% in the trade.
Nothing replaces experience and continued education and training. Impressive!
99.99999% of shop owners would not go to a junkyard to get parts for a customer. You are the man.
Perfect match for a junk truck.
His shop is probably very close to a junk yard. A lot of shops save parts. Or if they have a vehicle there with the same part that they know is good they will switch it out for the one they think is bad just to verify then order a new one. Obviously they arent going to do it for a cylinder head or a part thats a pain in the @$$ to replace, but a quick easy sensor or something, absolutely. A lot of shops also have motors sitting around that they replaced for someone so they can pull the part off the motor.
@@jacksmith2315 - I’m guessing it’s because the ice cream shop must be on the way….
The PR of NY no longer has junkyards. They are “automotive recycling centers”. La de da…
That’s going the extra mile, something you don’t see as much any more.
I wonder if your customers know how really lucky they are to have you as their mechanic. I hope you know how appreciated you are by your loyal followers !!! Thanks as always Eric O and family.
Can’t beat OEM parts even when they’re used.
My mechanic has been fixing my cars and trucks with used OEM parts for decades. And not a single issue out of any one of the repairs. Period. I didn't trust it at first. But, was made into a believer.
ESPECIALLY when they're used because they have a track record of working.
Mainly with sensors and electronics. Wheel bearings, brake pads, etc. not so much.
@@Garth2011 why not brake pads, $2 a pad can't beat that.
@@serge4856 Pads, you have no idea what they were. $10 crap pads or $80 oem pads
I think how realistic you are about this kind of stuff is a big part of why you are so successful. You knew this customer wasent going to want to pay $$$ for all new injectors, but other shops would have said that's your only option or it's not getting fixed. The fact that you were confident in your troubleshooting and that you were willing to go get that pick-a-part fuel rail and get it working for the guy, at a reasonable price, without a lot of fuss, puts you above so many other shops. and I bought one of your t-shirts, so I am a sponsor!
I always get a chuckle out of the “we could be wrong. By we I mean us.” It’s as funny as your other saying, “we were right. By we I mean me.”
As a retired electrical engineer who spent most of my career troubleshooting industrial machinery I am quite impressed with your troubleshooting abilities. And greatly entertained to boot! Love watching your vids brother !!
I've spent 35 years in manufacturing diagnosing and solving mechanical and technical problems and I appreciate Eric's deductive reasoning versus the part can work with a lot of guys working on a lot of different equipment and all they want to do is keep throwing parts at it till something stuck hey uses common sense and logic to figure out a problem I love it have a great day
Hey Eric! Automotive instructor in RI checking in. I have a student with these same codes in his Chevy truck of the same vintage coming in tomorrow for repairs with the same codes. This one doesn't have parts thrown at it first but I am going to assign him this video before we work on it. Chariho Career and Technical Center appreciates you!
💪🇺🇸
As an added bonus, you should have your student diagnose O2 codes.🤣
Make them pull up a chart for the Map and MAF so they can understand what value the sensor is suppose to be reading.
well Eric...you know you've arrived when the auto tech instructors are referencing your vids to our future technicians!
Make sure he loads his parts cannon properly!
🤣👍
I remember when OBD first started to come on modern vehicles with computers, I thought it would speed up diagnosis and repair.. instead it often leads people down the wrong rabbit hole as the computer is often compensating for the fault of something by affecting something else, in newer vehicles especially often in weird or unexpected ways.

I had the discussion with a career mechanic that liked the 'good old days' of purely mechanical operation. Nothing has changed with the internal combustion engine - it's still suck, squeeze, bang, blow. MAF and fuel injectors have replaced carburetors, cam phasers have replaced cam swaps, but oxygen sensors have replaced exhaust sniffers too.
OBD makes a lot of things easier to diagnose, but you have to know what you're looking at. Someone replacing fuel injectors for a rich condition is no different than replacing a carburetor for a rich condition. Without knowing that you have a leaking accelerator pump, or that you're running negative fuel trims, you are still just throwing parts at things. Data is data, and is useless to someone that doesn't know what the data is telling you.
Read about someone driving along and got a 'Fuel leak detected' message appear. So he stopped and looked all over and under the car, just to be safe. Found nothing, carried on. Looking into it at the garage, they found it was a poor connection on the speedo sensor.
Reason: the ECU knew what petrol quantity was being consumed, this was too much to what the ECU was being told it should be for the speed being reported, therefore there must be a leak.
Enough leaves under the wiper tray to make a ton of compost! Another great video!
Yeah, looking at all those leaves was killing me. OCD I guess. ;-)
I can hear Raymond now saying that this is a job for the assault blowgun 🤣
I think they were contributing to the rich condition.
Old fashioned fire needed!
The leaves are choking the intake🥹🥹
Eric you never cease to amaze me! I am a process control guy of 40 years and know PID loops like the back of my hands. You laid out one of the most concise, clear and methodical processes here to eliminate variables as you go. I teach a lot now and I tell my apprentices always remember there may be 15 or 20 things that COULD be wrong, but out of that list narrow it down to the top five and then go after the highest priority of errors and potential problem with the top 3. You did that flawlessly because you understand PID. Signal into the algorithm, the processor (ECM) looks at all related inputs and makes a decision. The device then (injectors in this case) must be able to CONTROL the variable that provides the final outcome. If an injector or injectors are junk all the good data "falls on deaf ears" and the injector dumps fuel like a fire hose the control is lost! My what a very interesting video. Kudos to a man who follows his convictions and must have a final solution. If the owner is not happy with your work, trust me there are 99 more out there given the same issues would pay you whatever you want to really FIX the problem, not just THROW parts at it!!! BRAVO!!
That concept of "smell the frustration" is just so true. I think we all understand the idea, but thanks Mr. O for putting it to words!
Mr Oism's
Indeed!
Mr O can smell again?
The smell of frustration after firing the parts canon is so strong that not even loss of smell due to the 'Rona' can cancel it out
Eric O is one cool cat! His channel is like a good movie or television show, you never get tired of watching. I'm not even embarrassed if he notices how many comments I've left. 😌
After watching the bonus footage, I thought to myself- "what a nice guy he is!" 😆
He is a nice guy....until someone from out of town calls him!
@@HouseCallAutoRepair Everyone is nice when the camera is on :)
@@HouseCallAutoRepair ultimately he has a business to run and employees to pay. So yeah I can see being less then polite to random out of town (CZcams) callers, chances are they are not going to help pay his bills and just take from his time.
Greatman great mechanic
Nice guys finish last, it's an old adage but it's often true, unfortunately. I've been burned many times by being the nice guy, a long time ago a friend of mine told me flat out, Pete, you're too nice and he was right, sometimes you just have be a total and complete bastard.
You brought a smile to me Eric when you said I’ll have to phone him up to see if he wants it fixed, ps let us know if he went ahead and told you to fix it
Awesome video as always! With what customer saved on injectors, perhaps he can go and buy a leaf blower…
Or a vacuum!😅
Maybe he couldn’t afford the big name brand at the time,we’ve all been there
Right yeah, so he can go blow whatever is left of that dang ol rusted out chevy into the gutter
For real
thinking the same thing....you know GM trucks have water leak problems, mostly due to leaves/junk clogging the cowl drains that go down around the fender area by the door hinges...lol
Another Good one Eric. Retired self empl Auto tech 37 yrs.
Good mechanic, hell yes. But the troubleshooting skills! You know how these things work, and they ain't simple. And the logical way you go through these issues, it's awesome. You should teach, because you are a master. I've learned a ton from you Thanks Eric.
only problem is teaching is not as lucrative as being the manager/HR person/salesman/service writer/tech/porter all in one...lol buy the way its more fun to get rust in your eyes and lose chunks of skin every other day!
I will NEVER forget the old man in the shop on my first day. "KID,.. I dont care if its a Car, a bicycle, a toaster, or the rollers on the kitchen drawer. If you dont know what its supposed to do, how the hell can you FIX IT???"
I agree whenever you decide to hang up your wrenches you could have a second career teaching at a tech college or something like that !!! Imparting your knowledge on the next generation of techs like yourself!!! You’re amazing. Keep up the good work!!
one more reason i drive an older vehicle. got fuel, got spark, should run. we need that again. great work, good man. the world needs more of you
You're a very good mechanic and diagnostician. Folks in your neck of the woods are very fortunate to have you. Thanks for sharing.
You are a good man and GREAT MECHANIC!!!! Don't know of any shops up north that would go the distance you did to fix a vehicle that the customer fired the Chinese parts cannon at several times.
You also have a bit of a gambling side to you as getting that junkyard fuel rail with injectors could have failed...But what are the odds that all the injectors would be done for?
It was a smarter move then buy all new injectors! Hopefully the customer did pay for your time and he could return the junk parts he bought.
At the least he learned a valuable lesson about cheap aftermarket parts.
Awesome diagnosis procedure! As a retired Chrysler and GM engine calibration engineer your process of how things could contribute to a rich condition are spot on. Chrysler measures barometric pressure exactly as you described (at least they did 2007 and earlier when I retired). I think GM does the same but GM ties each engineer to just a small portion of the calibration. At GM I was responsible for cam and ignition timing. At Chrysler I had pretty much the whole thing. GM had 20 engineers to do a calibration and Chrysler had 5.
I hate to say it I've worked on both and especially nowadays with Chrysler some of their engineering makes me wonder what they're thinking about when they do stuff GM I worked on quite a few of them and I found them to be a lot easier in the quality is a lot better and it's all due to engineering have a great day and thank you for everything you've done
So are you the one to blame for those crappy, junk GM cam sensors ? LOL
@@CraigGrant-sh3in Nope. Blame purchasing.
Beautiful diag on a rich condition. Loved it. Unfortunately, new parts doesn't mean good parts.
I’ve been guilty of shotgunning problems that I’ve encountered on our newer vehicles. It was hard for me to swallow my pride and acknowledge these newer vehicles are above my pay grade when it comes to diagnostic skills. I miss engine bays you could stand in, and with enough beers and a timing light you could fix anything. Love your content, glad you’re here to provide good knowledge and entertainment.
I think the issue with newer motors isn't so much that it's too hard to understand as more the fact that you need to be able to see and understand the data.
Older motors you didn't have a bunch of sensors to read, and didn't need a $5000 tool to see data. It was mostly by feel other than putting it together originally.
@Mck Idyl LOL been-there-done-that! 40 years ago!
Why put money into a engine that burns oil
@@mylanberg5419 Go price new or used vehicles these days. They are crazy expensive. Just lost my 2002 Saturn in a car accident last week; shopping for a decent used vehicle is insane with the price spike.
Thank LGB for the Bidenflation.
You know what that is? That's wrench'n BABY! Eric really does run a solid honest shop and I'm sure he's able to look himself in the mirror at the end of the day. Also appreciate his clear way of articulating what's happening and why. If you get tired of the shop life Eric maybe teaching could be an option, you have the talent for it.
been a fan for years and i love watching you work the puzzle , great job
Many times you’ve said you’re just an average mechanic trying to make a living. And I always appreciate humility in a person.
And I’m sure there’s been a smattering of problems that leave you scratching your head, at least until you figure out what was going on. MRI systems have driven me crazy on occasion also.
But, humility aside, your ability to troubleshoot is astounding. And your ability to translate that to amazingly great videos and explanations is without a doubt the very best on CZcams.
Outstanding video!! Thank you, Mr. O for taking the time to make these. I think we all know it slows you down and can be frustrating just making the darn things, but just rest assured we love them and appreciate your efforts.
😂😂 I’ll give you a call (not) and let you know how much I appreciate it. 😂😂. (I’d never do that, by the way.) Be safe.
More shops need to think outside of the box like you did on this. Great work Mr.O. it's really enjoyable to learn from you !
Great job as always. I love how customers can justify spending a pile of money on the parts cannon instead of paying a professional to diagnose it correctly.
Finding a good professional can be hard. If the owner had used gm parts instead of cheap junk he would have fixed it himself. I have learnt a few hard lessons with cheap parts myself. Eric professional as always.
Not easy to find a competent diag guy now a days.
"Gotta call this guy and see if he wants it fixed now"
That was PERFECT.
Besides, you're right, we wanted to see it fixed.
Once again, Eric, you have shown us all why NY is lucky to have such a GREAT mechanic in their midst! I worked in and then ran our family appliance repair business for the last 30 of its' 61 years in operation and have the same meticulous and structured thought process as you do. What always came as just plain logical to me usually amazed many of my clients. You are one of a dying breed of people who CARE about what they do! Thank you for your videos!
Please give us an update on what the customer decided to do! Inquiring minds want to know!
Great problem solving Eric. Makes sense to think about what could possible be causing that problem and then eliminate them one at a time "or eight at a time" LOL.. Thumbs Up man !! 👍👏
I am super impressed with this fix. I wouldn't have thought that the injectors were the cause of the problems. Excellent diagnosis and excellent fix.
He could have saved himself a thousand bucks and a lot of frustration if he just brought it to you six months ago.
Kinda what I was thinking. Makes you wonder what the initial real problem was.
@@SouthMainAuto Some people can't leave well enough alone.
(I had a wife like that..)
"Relax, all right? My old man is a television repairman, he's got this ultimate set of tools. I can fix it."
Unfortunately the Information Age has made everybody think they know what they are doing. I work in an ER, we have patients all day long arguing with the DR over something they read or saw over the internet.
In this case, the truck would have been fixed by guessing if he weren't throwing wing ding junk parts on it.
@@mph5896 "And remember, if I can do you can do it!". 😉🤔😅
@@mph5896 Jeff Spicoli ftw!
Bought it new, I have 07 Silverado Crew Cab 4.8 wt142,000 miles on it. As of yet have never had engine or drive train issues. I have never been broken down on the road, Love my truck and dependability of it.
For what it's worth.....that last piece you grabbed while at the junkyard, says it all. A decent mechanic looks at it all. Excellent video. Love the channel !
I love the way this guy explains things to us old DYI guys .
You have integrity. You want to do things right, and deliver a good work product to your customer. Hats off to you.
This is the second time i have watched this video. Thank you for driving home the ebay/Chinese Junk fact! I always suspected but never had proof. Also not only are you the best mechanic on CZcams You have integrity!
Chinese parts for lawn mowers are mostly junk also !!!
Eric,
You say that you're not a great mechanic but you do have a penchant for being able to troubleshoot and diagnose problems without a lot of "let's try this and see what happens".
That right there puts you ahead of the bunch in my book!👍
Eric: I truble shoot special computer hardware. I get an E-mail with some of the discription of the problem and I am suposed to solve the problem without the full details. I have to ask alot of questions and give them a direction and ask for the results.
I have been doing this for many years - HOWEVER- watching your videos is very helpful to hone my skils to diagnose.
Thank you forhow you diagnose before throwing parts at a problem. Keep up the good I mean :GRAT" diagnoses and being honest. It is great to see there are still honest people like you and IVAN!!
Your channel has really caused me to do things so differently, to use the credit card only after all the evidence is in. Thanks. I still have friends who fire the parts cannon first, but I no longer argue.
Wow, we must know the same people, lol. Not to mention if you change 3 items with aftermarket crap, you now have 4 problems instead Of just the one original problem
This was just so good! Love your stuff Eric. Thank you for being you and letting us watch you being you. It matters! Btw, happy to see your "sniffer" is working again.
these are better than regular manufacturers training classes. thanks for the time you take to do these videos, they are a tremendous help for adjusting a proper diagnostic mindset from parts replacement scatter shots.
Another amazing video (these troubleshooting ones are my favorite) thanks again for post so many new video. PS your a excellent tech, and explain things easily to understand thank you 😊
Thanks Eric for the closure. I certainly appreciate it. Also loved the bonus footage. Let us know if the customer didn't want the repair. We could all chip in a few dollars and help cover it for you.
Eric you are awesome. Man your critical troubleshooting skills are top notch.
I have a 2010 Yukon XL Denali and have been going mad about the rich condition in both banks pinned at -30. And changed the fuel pump and Charcoal canister and MAF sensor. This truck I’ve done lifters on with this LS AFM engine. But your video is only one that I’ve found that now possibly points me in right direction. Fuel injectors. At 240,000 miles maybe it’s the cause I will hit you back. Great video and as you say your rambling but to the right ear it’s teaching, in the best way. Love it and thanks ☘️🍻🖐🏻 Kevin from NJ
Eric! The reason I watch your channel is because I know you're a great mechanic! Plus you are honest and have a lot of integrity. If you say it's the Chinanizim injectors. It's the injectors. And I am learning how to do my own repairs. I doubt that this customer will say no way? But I know you wanted to know as well 😏. Remember I watch you because of your great wisdom. If I can do it. You can do it. 😉😊😊😊😊. Thank you for sharing your experience and knowledge.
Speaking from one tech to another, I really agree with your diagnostic approach! Getting an accurate repair history is a huge pain most of the time but having good test parts is a great time saver!! Appreciate you taking the time to make videos!!
I hate to say it sometimes customers like kids they don't want to admit they screwed something up but hey bottom line is a problem got my head into it figured it out and now the problem is solved it doesn't matter who's responsible it's fixed that's the main thing have a great day
great video Eric...love your determination in giving us the results in your troubleshooting and what you think is the problem. and yes, you are a good dude!!
I found this video especially helpful in fixing my 2008 GMC Sierra with the P0172 and P0175 codes. Thank you Mr. O
Been reading through the comments and non have described the issue ?
Your instincts and experience are amazing Mr. O! I learn something everytime I watch your videos.
Honestly trying to help people is your greatest strength.
My favorite kind of SMA video, Parts Cannon!, kaboom!
Found two listings for mostplus injectors 1: flex fuel 5.3l and 2: 80lb non flex fuel application with the warning "Note:These are not stock direct replacement, the flow rate is 80lb 830cc require ECU tuning after installation."
So good chance they were not bad injectors just not the right ones for the engine and not even needed as we learned from the ace at SMA!
Keep on truckin' your the best!
Absolutely great diagnostic and troubleshooting skills you have, young man. It's very easy to follow along with you as you explain your thinking and your theory of operation. Thanks for taking us along.
This is a fundamental and wise video. The minutes spent listening to Eric O. will benefit hours and hours of lives spent.💚👍Thank you.
I wish I lived nearby this guy is amazing and I got a Chevy that needs his help!
this was a good one. I got a kick out of the "forest deposit" on the cowl. I thought for sure he would have made a joke about that.
You sir, are one helluva detective, gathering the evidence and weighing the facts !! 👍👍
As soon as you started it up you could hear the difference. She purred like a kitten. I listened to my buddy and put aftermarket Bosch injectors on my 87 Camaro, she leaked at the rail and sounded like a hammer factory. I couldn't get them to seal at the rail no matter how many times we took it apart and put it back together. I bought a rescreen kit for my factory Rochestors and put new screens in them just in case beforehand. I threw those on, with new O-rings with a dab of vaseline for insertion. She started right up and purred like a kitten, the quietest I've ever heard her run. No sealing problems whatsoever, just popped right in. Smooth.
Great job of deductive reasoning and the 1st extreme rich mixture video I have seen. Learned a bunch and thanks for the great explanations along the way. 5 stars on this one.
Interesting video in the way that it's not diagnostic that helped solve the problem, but experience you've accumulated throughout the years.
Another great video. You do the industry a terrific service by making these videos that people will refer to for years to come.
Love everything about your videos and attitude. Fun to watch the roller coaster we all ride through your perspective. Thanks for all you and your family do to make this world a better place.
You are just amazing Sir big heart. Great repair. Awesome video. Take care thanks 😊
Congrats on getting your hydrocarbon & organic-molecule detection system back in working order. Tough to detect gasoline in oil without one of those.
We had a guy bring in an outboard where his "mechanic" replaced nearly everything chasing a run issue. We have since spent almost a year replacing aftermarket components 1 at a time as they have failed.
Fantastic! When I grow up I want to be just like you… an analyzing PhD of all things vehicular! Wait… I’m 72 years old. Oh well… I’ll continue to watch… be fascinated… and learn. Thank you and God bless you Eric.
Well worked out Eric, great result, and when it's in the junkyard shortly, as it doesn't have too long left, you'll know where to put your hands on some good secondhand Chevy injectors and a few other OEM sensors. Very informative and entertaining as always 👍👍👍
I admire the way you diagnose things, and wanting to "make it OEM right"
Good diagnostic process. Check everything that can cause engine to run rich. Then parts cannon all the bad parts cannon and get that engine running right.
Always look forward to your videos amazing job I get out of work from working on heavy equipment to watch you work 🤙🤙
Eric I've been watching you for over a decade now and every time I come back I see you nail it. Broken cars fear you! Well done boss
Back in my younger days (mid 1980s to early 1990s) I ran up on the same problem with a v6 Chevy engine in a Buick. Emissions are off scale, performance bad and fuel usage terrible. We had to practically test each component separately. I was pulling my hair out (had a LOT of hair then) until I compared the fuel injector numbers, they were entirely different. It turned out her husband had changed the injectors out with a set of reconditioned ones he bought. The ones he installed were for the same size engine but for a different year. If memory serves me right the injectors he installed were for the same size engine but about 4 years younger and used different resistance values in the firing circuit in the control module (computer). Installed the proper injectors and everything ran great.
So great to watch you diagnose that fault. I had that exact problem on a Caterpillar 3412 marine engine. Customer replaced all 12 injectors with aftermarket ones. Then….it had no power and was smoking but insisted the injectors were fine. After 2 days of diagnosis we put the old injectors back in and it was fixed! Don’t buy aftermarket parts folks , that’s just my opinion.
Welcome back to the south main chivy channel
I love when you tell us the customers problem at the beginning because I make my call what I suspect the problem is and then actively anticipate if my diagnosis is right. I totally called injectors. Love seeing your thought process in action.
great work as usual I like the methods of troubleshooting you use.
Keep doing what you doing man because you teaching us a lot of stuff and about the fuel injectors that could be a lot of your problem don't buy Chinese parts but I made in USA we love you man keep working on the internet
I would love it if you did a video on fuel trim and went a little more basic to explain to us idiots what everything is doing. Cheers brother.
It's pinned at the top... video about fuel trims. In short, the fuel trim is a mechanism used by the computer to adjust how much fuel it delivers to the cylinders, based on the data it receives from the various sensors, to maintain the desired lambda. It can add, or subtract fuel. If it needs to consistently correct in one direction, it stores the average in the long fuel trim. A perfectly running engine will have the LFT at zero and the SFT jumping both sides of 0. The number is a percentage.
One thing that is a constant on this channel. You like your original parts over pattern parts. You are not averse to going down the scrap yard and procuring parts at a reasonable cost. Fixing the vehicle correctly with as near to original parts as possible. for the best price possible. What more could a customer want.
Another good one. I do appreciate your work. Watching you has helped me troubleshoot a few problems that I encountered. Like tracking down wiring issues. And now cheap parts!
Welcome to my world, I deal with this stuff all the time. Good Job, you do your diagnostic like I do. That's why I enjoy watching your videos ☺️☺️☺️
Jobs like this one can be some of the most difficult, not necessarily because the diagnosis is difficult, but because no matter what you tell the customer, they’re going to tell you “but I already replaced that!” People don’t seem to understand that buying the cheapest garbage they can find on Amazon is pretty much always a bad idea.
OMG, I cant believe I found this video today!!!! Thank you !!
I have the same issue with 2013 GMC Sierra 1500 5.3L, Flex fuel, it started 2 weeks ago all of a sudden, it started eating gas, I have the same codes, plus few more, needed to change oil pressure sensor, and it was burning alot of oil. Vehicle parked. Not wanting to take to shop, thought I would do some digging around, watched this and that video, not sure where to start. I cleaned MAF, changed valve cover gaskets, glad I did, grommets were leaking, cleaned PCV valve but as a note I took off the valve cover I could smell alot of gas on drivers side.... strange. Changed oil sensor but still would not hold pressure, so changed oil / filter again (was only 3 months since last one and only driving 150 km per week) and notice oil seemed to be watered down or way to thin and not have any real lubrication feel to it, but no contaminants, it worked, still gulping down fuel. I will have to go over the live data again and compare to your data, although the fuel trim #'s aren't as bad as this truck, and now only have P0175. The only thing I did different during the last 7 weeks was not go to the only two gas brands that I normally stick with cause I can tell the engine does not like some gas, and some just run right through it, seriously, no joke !! It was just too bloody cold, so I went to all the closet gas stations of different brands and within weeks the issues started. So I was thinking of EGR valve next, but nothing was mentioned here. Will try looking at MAP first before the injectors and cross my fingers... You saved the day..
Check your alcohol content on a scan tool. Its prob really high when in reality its low. If thats the case reset it with a scan tool and change the oil if necessary if contaminated with fuel.
You need a decent scan tool first. Autel makes some lower end ones for a few hundred dollars. TOPON has a relatively cheap bidirectional one for $800. Without data you are just guessing. About a 70% probablity that its the alcohol sensing data thats off.
@@mph5896 thank you, alcohol sensing data reads 62.7
@@leonardodavinci303 thank you, I do have the lower end Autel scanner. Alcohol sensing data reads 62.7
@@Kayuu7 Nice. Easy fix.
You amaze me every time. Your clients are lucky to have you. I was told, "to diagnose my 2002 F150 4.6L rough idle, they would have to open it up to see if the timing was off. $1000 CDN just to check". Ran outta there I'll tell ya. You are incredible. I wouldn't be surprised if tech schools used your videos for training.
Kind heart you have. Customer first.
Gotta love the old Amazon and ebay parts problem
What a good guy!! 😆. A rare find these days.
Nice Diag. I would explain the difference between a MAF engine vs. speed density fuel strategy. When non-MAF engine runs rich, I always check for low compression on one or more of the cylinders on the rich bank, if it has real O2's and not a AFR. Because it won't burn efficiently and it will throw more O2 down the exhaust and the computer will richen the whole bank.
What do you mean by "real O2s and not an AFR"? Also why only MAP, would a misfiring cylinder not cause a potential rich condition on a MAF engine?
Thank you. Excellent diagnosing and repair.
Well done Eric and don't give up on the rambling it's who you are and what you do to reach the end game through experience and hard work.
You make me smile when you have success and that's a huge bonus you give America and the world makes you a hero. "If I can do it, you can do it" is such an inspired brilliant closer to shear hard when your work involves analysis as just one part of your craft abilities as you have such a wide range of skills.
Every time you publish yet one video you make the world a better place as shared knowledge with local tradesmen working in one town until the internet and in particular CZcams the local guy could never achieve what you do in thousand lifetimes.
I'm just learning how much time is involved in editing video clips, you the best and well done from an old boy who worked for fifty five years and now wishes he had recorded his life's work.
Ahead or two before I retired from work, mostly as an industrial gas engineer uniting what would have independent skills when I was an apprentice, electrical design and maintenance in a tannery with so much varied specialist plant for leather production. A great training base for a kid who had attended a technical school, ages, 13 to 16 and taught, more lectured by craftsman who had won the Second World War with millions of others and then during the peace obtained the academic qualifications to teach their life skills.
I required an extra certificate to keep my gas license. The lecturer had ten of us for the morning, me with nine others who had been friends in town and didn't know me or me them which
didn't matter in the course of one more day.
I had only worked at the college a few times brought in to troubleshoot some problems. I did what was asked and moved on as you do as a sub contractor.
One was in my most interesting couple of hundred best ever weeks work and as it was in my town it was particularly satisfying. Redesigning a ventilation and warm air scheme serving a lab area teaching electrical apprentices, twenty in the morning and the same for the afternoon, a plumbing and heating apprentices. 400 sessions a week. For the first time in twelve years since the building was opened the trainees and staff had a system that worked longer than once a year. Fixed for the start of the heating season, when one key item, the fan delivering the warm air would burn out and never work again until budget was found a year or two later and no engineer realised the flawed design.
The result of efforts and success was a group of lecturers observed my working methods and offered me job subject to acceptance and I made a mistake not to take the offer and stuck to my troubleshooting. I should have branched out and shared my knowledge through a college at the age of fifty.
I didn't have the confidence to become a lecturer, so you're living my dream Eric, congratulations.
Eric I have watched you through a lot of years and I know I would trust your judgement and this man will pay you and thank you for all your efforts.great job.
Your diagnostic process is awesome man keep up the great work
Keep up the good work!! You are the kind of mechanic everyone is looking for......honest and knowledgeable!!!
I been at a dealer as a Forman for 22 years still learning from this guy !!!!
