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.

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.

99.99999% of shop owners would not go to a junkyard to get parts for a customer. You are the man.

Nothing replaces experience and continued education and training. Impressive!

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 !!

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!

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!!

Can’t beat OEM parts even when they’re used.

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

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!

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.

Enough leaves under the wiper tray to make a ton of compost! Another great video!

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 RU-vid. 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.

After watching the bonus footage, I thought to myself- "what a nice guy he is!" 😆

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!

You're a very good mechanic and diagnostician. Folks in your neck of the woods are very fortunate to have you. Thanks for sharing.

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. 😌

Awesome video as always! With what customer saved on injectors, perhaps he can go and buy a leaf blower…

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

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.

Beautiful diag on a rich condition. Loved it. Unfortunately, new parts doesn't mean good parts.

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 !

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.

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 !

Ran into another problem and re-watched this video. It's my third time watching. Love the logic. Thank you.

You have integrity. You want to do things right, and deliver a good work product to your customer. Hats off to 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 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!👍

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 RU-vid You have integrity!

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.

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!!

He could have saved himself a thousand bucks and a lot of frustration if he just brought it to you six months ago.

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.

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.

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 instincts and experience are amazing Mr. O! I learn something everytime I watch your videos.

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.

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 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.

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.

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

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.

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.

You sir, are one helluva detective, gathering the evidence and weighing the facts !! 👍👍

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 😊

Honestly trying to help people is your greatest strength.

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.

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.

I wish I lived nearby this guy is amazing and I got a Chevy that needs his help!

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

Another great video. You do the industry a terrific service by making these videos that people will refer to for years to come.

I have been working on my truck for three months and trying to find the source of the rich condition. Your video helped us realize the brand new injectors we bought were garbage. We cleaned the originals and reinstalled and it’s running perfect. Thank you!

Keep up the good work!! You are the kind of mechanic everyone is looking for......honest and knowledgeable!!!

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

This is a fundamental and wise video. The minutes spent listening to Eric O. will benefit hours and hours of lives spent.💚👍Thank you.

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 know I am commenting on a 2010 dodge grand caravan and not this video. I have been a doing my mechanic work on my vehicles for about 50 years so I have a good idea of what I am doing. I want to thank you for making and sharing these videos. I watched your series on changing an engine on my caravan and changed my engine successfully. I have pulled engines and transmissions on older cars but I had no idea how to do so on a cross mounted engine but you showed how to do it. I just replaced a front wheel bearing, brakes and rotors Also just watched a video on rear wheel bearing because that is next. I really enjoy watching your videos because you go into so much detail. Keep up the great work you must have been sent down from heaven to save people like me from making mistakes A great big THANK YOU to you for saving the day.

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.

Ive been in the business for over 14 years, and ive never seen a mechanic thats as incredible as you. Willing to take time to go to the junkyard and pull parts that you don't even know if they work, to try and fix the problem for the customer. Thats integrity, and just pure awesomeness. Keep up this awesome work Eric O. I know you're like me in the sense that you enjoy going to the junkyard. Its one of my favorite things. Unfortunately our best and long standing yard closed and sold out to some affordable housing BS. So besides the scumbag pick n pull, we only have a couple good yards left...PnP charges individually for EVERY single little thing and its asinine. I only go there if im absolutely desperate because the others are closed. You Rock Mr O!

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!

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.

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.

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!

You are just amazing Sir big heart. Great repair. Awesome video. Take care thanks 😊

Eric do you have room for one more friend. Fyi I live in Washington state. I always feel like I'm watching my best friend and we've never even met. No homeo but I love you man. I'm 39 so I relate to most everything you talk about. Keep it up for all of us and so we can keep our chevys on the road.

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.

I been at a dealer as a Forman for 22 years still learning from this guy !!!!

Congrats on getting your hydrocarbon & organic-molecule detection system back in working order. Tough to detect gasoline in oil without one of those.

Eric you are the greatest mechanic on the planet! Watching you make it look simple. Thank you for the clear direction on using OEM or aftermarket. I have always taken the safe route (oem) with out proof only to be laughed at and told your waisting your money those aftermarket parts and OEM are the same. I say in looks only! Thank you for that!

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.

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 RU-vid 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.

I’m a Hvac tech they taught in school of someone was there before backtrack there steps which you did. I’m a diy and one thing I have learned is factory parts. Especially when it comes to electrical and mechanical. Awesome job Eric I always learn . I a Hvac RU-vid channel I love he is just like you very humble Hvacr videos thanks again for the video

Welcome back to the south main chivy channel

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.

Great video! Loved watching your logic and trusting your gut feeling on the injectors. You do amazing work and go the extra mile when so many others don't.

This is one of those shops you can actually trust with your vehicle. Fantastic fix as always.

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

Glad to see your sense of smell is coming back

Gotta love the old Amazon and ebay parts problem

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.

First thing that stuck out to me was that baro reading at only 12.5psi. Should be around 14 or so in the southern tier

This was a perfect overview of fuel trim issues in my opinion. You chose a great logical starting point and worked your way up. Really helped me understand the concept of these types of issues and how to troubleshoot them.

It is jobs like this that inspired the creation of the shop work rate chart that had a special rate for repairs attempted by customer.

You are the man! No one says Chevrolet like you do. Every time I pass by the local dealership I hear your voice and I chuckle. It was very interesting to see that used OEM injectors from a junked truck are still better than new ones from eBay. I think you are a great mechanic because you took the time to get the little rubber piece for the purge valve as well as the fuel rail to make sure the customer's vehicle is up to snuff before you talk to them and you care about your reputation. Thanks for the explanations of how you did what you did. Good Luck and all the Best to you and yours.

Great find. Just another reason that I prefer oem parts when I can get them.

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.

Your diagnostic process is awesome man keep up the great work

It's always interesting to watch a professional at work and follow the line of thinking. 👍👍

So did the customer wind up paying? Great video, glad you helped the man out hopefully you bought him enough time to get into a newer truck if the frame is really getting that bad.

You are a very generous man Eric. You invested time, money and your stash of spare parts to fix this car which in itself has not much time in this world before it goes to the scrapheap. You even acknowledged you might not get ;aid, but you will still ship it. Very nice Eric, very nice.

You sure get a lot of Chevrolets!

Eric O. Never met you and probably never will since I'm in Carolina but.....You a good guy and a great mechanic!! You are an inspiration to the up and coming guys and gals for sure!! God bless you and your family and I will stay tuned!!

You make working on cars seem like fun . Thank you for the videos!

Eriic you forgotten more about mechanics that a so called tech. You are in a league of your own. MASTER TECK. Brilliant.

Eric, you never cease to amaze your viewers. Great troubleshooting! Obviously experience plays a role in your knowledge. Thanks for all the extra work you have to do to bring your exeriences to RU-vid. Cheers

This video proves what I have always said. Aftermarket is great for exhaust, alternators, suspension, brake parts. Some items like fuel pumps, injectors MAF sensor should only be OEM. It is more expensive, but cheaper in the long run. The hardest part for a DIY mechanic like myself is once you put in brand new parts, you move on to something else because you think new has to be good. This video proves other wise. Great video as always......

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

Bravo Eric, You're an OK type of a guy. You deserve compliments for what you do. So I want to compliment you for being fair and also a good mechanic. Congratulations Eric.
