Parts Cannon Special: Rich Running Chevy Truck P0172 and P0175

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!

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.

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!

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!!

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.

[@suttoncoldfield9318]

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.

[@scottjohnson4319]

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 KZbin. Outstanding video!! Thank you, Mr. O for taking the time to make these.

[@davidzelkowski9948]

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.

[@michaelpressman7203]

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

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.

[@johnnyblue4799]

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.

[@johncraig406]

I admire the way you diagnose things, and wanting to "make it OEM right"

[@johnalexander4356]

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!

[@hanksbud2544]

Thank you. Excellent diagnosing and repair.

[@rider547]

Great video! Another example of how “junk” parts can make issues worse than when you started. I just wish I would have known this a long time ago before I installed cheap parts on some of my vehicles. Keep up the good work! You’re the man!!!

[@rickcoleman8903]

great work as usual I like the methods of troubleshooting you use.

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.

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.

Gotta love the old Amazon and ebay parts problem

[@IronRiviera]

I always like to try and get even "the little things" while I'm at the junkyard. Good job.

[@danielsilva384]

Your diagnostic process is awesome man keep up the great work

[@Burton1973]

You are the best 1999-2006 Chevy truck mechanic ive seen to date. Glad I found your channel. ty very much.

[@littleshopintheshed]

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.

[@MMAunderbelly]

Welcome back to the south main chivy channel

[@gregfleck4140]

I gotta love your honesty and integrity wished I lived closer to u

[@sober265]

Really enjoying all these videos lately. Thanks for taking the time to make these for pall of us to enjoy.

You sure get a lot of Chevrolets!

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 KZbin 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.

Honestly trying to help people is your greatest strength.

[@stevet1963]

Great deduction from a great teacher, with a heart of gold Keep doing what you do , it gives you a warm feeling inside 🙂 Just don’t lose too much money 🤦🏻

[@Shirkatron]

I’ve been there… Had a kid bring me a 2005 Subaru Outback Turbo. Concern was stalls at stop lights when pressing in the clutch. I’ve heard of the Parts Cannon before but this kid found a “parts UZI” with a 30 round clip. He replaced the MAF, MAP, Throttle body, AF Senson, Rear O2 sensor, injectors, and installed a used ECM. Every part was from Rock Auto or some flee bay site. Thankfully the kid still had the OEM parts he removed. Turns out it was just a slow responding AFR.

[@JenniferFuchek]

Just because cheap fits doesn't mean it works right! ♡

[@spelunkerd]

What a helpful teaching video. I especially like the way you took us along while you were thinking, going through the list of causes in your head. MAF, stuck purge, stuck PCV, contaminated oil, fuel pressure, injectors, programming, etc. Brilliant idea to scrounge a fuel rail, I think most would sell a whole set of new injectors.

[@michaelsilva3513]

I wish I had a local tech like you sir. Thank you for all you do. I’m learning alot
