No Parts Required Rich Running Chevy Truck

In this video I have a look at a customers 2012 Chevy Silverado that has the classic P0172 and P0175. It also has a P0101 so we'll have a look at that too. These are both pretty easy to correct.
-Enjoy!

Mr 0', I just wanted to say as a non automibile mechanic, although diagnostician of 3 decades of H.V.A.C. systems; thank you for your videos. It means alot to all of us! Whether or not we work on vehicle or whatever...thank you sir! Much respect!

[@michaelfrohn255]

Just a heads up, we mechanic’s are doctors 😂😂😂😂 so please refer to him as dr o 😂😂

[@michaelfrohn255]

Just like you are a doctor of hvac! We are just paid less 😢😢😢😢

[@JohnRodriguesPhotographer]

I spent about 40 years working with computers from handheld to mainframe. His troubleshooting skills are off the chart. It doesn't matter what you work on, you can learn from his thought process and logic.

[@michaelmankowski5092]

I think this and all your videos are great and informative. Although I just can't afford some of your scan tools. I do learn a lot from them. I do have a cheap scan tool that does some things like fuel trim. Oh ya, thanks, DR O.

[@mrfishbulb7187]

​@@michaelfrohn255 There's a difference, doctors only practise medicine. Mechanics are supposed to get it right first time every time!😂

[@Railtech_63.]

Thanks again for common sense repairs, we need more trustworthy mechanics like you and your shop that believe in doing the right job. Taking care of your customers.

Agree. I had a 91 mazda b2200. Less that 40k on it. California. It failed smog miserably and was tagged as a gross poluter for tge rest of its life. Took it to the dealer. They said the cat was bad. Paid to have replaced. Still gross poluter. Took to a couple mechanics. And one guy got all the smog readings and pondered for a while, staired at the MAF sensor for a while, then offered me $500 for the truck, that hesitation looking at the maf made me think twice. Took it home. Sprayed carb cleaner and what do you know. Fixed. Scammers everywhere.

[@markmalikowski4971]

Every thing you do is an education for us. And without a good scan tool, I'd have zero clue what was going on. Excellent video!

[@FishFind3000]

Sometimes getting manufacture specific info can be awesome. For my ford I use forscan and I got a check engine light for a map sensor out if range code. When I scanned it was saying the code was not active but it keeps the light on. If I took it anywhere they would have swapped the sensor and the harness. I just rest the code and had no issue, bought some cleaner and cleaned all 3 sensors and have had no issues since. Just a one time freak out if range code.

[@freddiejupiter442]

The extra product leaking around the button is how CRC is trying to get you to use more than one can every couple years.

[@ricka5471]

Great diag. Your troubleshooting skills are 2nd to none. I always learn something from you on each video. Thanks and please keep the videos coming.

[@slocavky]

Great explanation of how the long term and short term trims and how they work. That made sense.

[@chrisnorden8043]

Great diagnosis and repair as always. However, I'm now sad. Reminds me of the 2013 Silverado I had, may she rest in pieces.

[@patrickzadd5215]

Eric in 1986 I earned an Associates Degree in Auto Technology I passed all 8 tests and was a Master Technician I consider myself a skilled, experienced Mechanic I’ve been watching your channel for a few years and you’re the best I’ve ever seen keep making magic happen in Avoca note….some of the things I have learned Fluid film is amazing Astro pneumatic tools are legit don’t be stingy with the Brakleen be safe Z-man out!

[@allanwainwright1478]

YOUR POINT BEING ???????

[@martijn-vels]

You know you're hooked onto these videos when you yelling "CHEVVY THUNDER!" synchronizes perfectly with Eric's 😅 Re oil burners: I know people like to hate on BMW, but my BMW (328 XI) has non measurable oil consumption at 90K. Ok, no dipstick, skeptics could claim the electronic oil level display is a lie, but I guess the dealer pull out nearly as much as they put every 7k.😊

[@lexteakmialoki5544]

Master class from one of the best ever. Side note: I been getting bad spray paint cans recently, tube inside falls off. They figured out spray cans in the 60's... Now they can't even manufacture those properly. Junk Junk Junk.

[@CycleGeezer-cq9lm]

I gotta say again, you are an excellent and entertaining teacher. Really enjoy the logical conclusions you arrive at and the excellent clarifications on how you got there. You take a case of complete befuddlement and when you are done explaining, I almost understand what I thought you were talking about. In other words, GREAT video!!! Keep it up, we're loving it!

[@pickles5150]

I just found you on KZbin while convalescing in a hospital bed after a hip replacement and was very impressed at your knowledge base. I’m not a mechanic but I consider myself a bit more than a DIY’er especially for a Priest. Wish there were more mechanics like you we could rely on.

[@rawcado]

I'm not a priest, but while working on vehicles, I find myself saying, "Good Lord, now what?" :D

[@DIYDaveOK]

I had a spray paint can do that same thing (actually worse, just spewing everywhere ) and nearly ruin a paint job I was doing on the bumper of my daughter's Corolla. Really infuriating. Thanks as always, Eric!!

[@mayhemsmaster5050]

I thoroughly enjoy your videos, and always learn a great deal from you. Whether it be a scantool or a nut and bolt repair, they both are phenomenal. I hope you do a video on the Odessey... I think it would be awesome. Thank you for teaching this old dog new tricks.🙏💜

[@mikechiodetti4482]

I'm keeping this video. You explained the relationships of fuel/alcohol content, fuel trims/maf readings and CRC can, not the actual cleaner problem. When you explain it, it makes sense. Thank you for this video.

[@luv2yt]

I'm keeping it too. Thanks Mike, great suggestion.

[@richardthomas1743]

Hey Eric! You should be thanking Chevrolet for making it possible for giving you LOTS of problems to make videos about! LOL

[@fixingitrightish]

He has started out videos before thanking Chevy for making him lots of money haha

[@chimrichalds5205]

It's crazy how many of his videos are newer GM products. I legit can't tell if that's all people buy around there or they're just that bad. Ford vids are few and far between and not many imports.

Wow! Just ran into this last night on the in-laws truck, alc content was pegged at 65% running fine after a reset with the scan tool.

[@Bucketheadland1]

You'd have a blast plugging into my Burb.. 240k and counting 👊💪🤑

[@MikeBrown-ii3pt]

As someone who's definitely more nuts n bolts than technical/electronics repair, I LOVE videos like this. They prove beyond reasonable doubt that even modern vehicles can sometimes still be repaired with simple, inexpensive fixes.

[@sidvis7235]

True, provided you have an expensive analyzer and know how to use them. I'm a retired mechanic, and it just wouldn't pay to purchse one for the possible one or two times I may need it. So, I'm at the mercy of other mechanics who can't read and interprete data with the accurracy and efficiency that Eric posesses. Eric O. you are a NY treasure. People like you shoiuld never pass away or retire.😉

[@coreycheatham06]

Hello! I absolutely enjoy your break downs and explanations of everything. You're such a great teacher! Thank you!

[@Starchface]

Your depth of knowledge about all these modules and engine management systems is outstanding. You play that scan tool like a violin. I'm starting to cry just thinking about it. Well done good sir.

[@johnmehaffey9953]

Eric you’ve entertained and educated millions on you’re channel, thank you for your work on the autos and your work on setting up the posts for the tube, hi from Ireland, ps Eric certainly not boring very interesting you’re a magician with the scan tool

[@kylehiltner4185]

Chevy also has a computer update, at least they did for my 2010, that fixed some of the programming logic. I was having a to reset the alcohol content once a week as the truck would get really hard to start from cold. I had my shop run the update on the computer and have not had a problem since.

[@fixingitrightish]

Their programming "logic" is so ass backwards. In my impala if it is super cold outside and doesn't reach operating temperatures within a certain amount of time it throws an error for the temp being out of spec. It doesn't have a code for the engine being cold so it throws the code for the engine overheating instead, because wtf else is it supposed to do lol. It then turns off the temp sensor, disables the air conditioning and kicks the radiator fans onto high. My car is cold and it's actively making it colder.

[@craigunwin8483]

Very good video. I'm very interested in your scan tool videos and how you figure things out.

[@smiles7631]

Used to be in the automotive field years ago, moved on to maintenance sup at a big warehouse. Still work on cars on the weekends. I enjoy the scanner videos and learn what to look for from you. Keep up the great work fella.

I would never spend any time under my own hood if I was in your town. If I watched every video you ever made, I would still be impressed by the next one.

[@kevinelsdon273]

“I hope I am not boring you” lol! Never! Your troubleshooting and logical skills never bore anyone! Your wealth of knowledge is also used by many! Tack on your wonderful family, and joy of doing what you do is amazing! Makes me want to move out to your neck of the woods from the west coast and come work for you for free just to suck up your knowledge!

[@richarde.beatty838]

actually, I appreciate the hands-on-actual diagnostic manner you have, you explain well, and give the alternative cause. This type of video is priceless training. Thank you and Mrs O

[@glenharper3136]

Always learn something from your videos Eric. Thanks for making them.

[@scottnusser6232]

Great info on alcohol content and reset for fuel trims! In the real old days we adjusted trims by first removing q-jet carburetor and grinding the anti-tamper plugs out that covered the mixture screws in carb base plate,then re-install on engine and adjust to best manifold vacuum. If you were real high tech you would use a 3 gas exhaust analyser and set co at about 1.5 to 3.0 percent. This is back when men were men and hotrods were built in Detroit.

[@SouthMainAuto]

And now men can be women or non gender specific and choose their pronoun and hotrods are made in China 😅

[@dav1dsm1th]

You could do a target competition with Mrs O, shooting CRC cans in front of a nice log fire. They look like they'd make a nice whoomph accompanied with pretty flames. Stay safe out there.

Really enjoy your videos! I bet they have been running that truck super rich for a while and the gas vapors in the crankcase remains for a while. I used to own an old '85 Chevy that was owned by a local propane company that was running a propane setup complete with a small tank. I took all that stuff off and bolted up a nice 4BBL carb and installed a new gas tank. Lot easier to gas it up than constantly need to get propane. It always smelled like a barbecue grill when it ran, even on gasoline!! Just couldn't get those vapors out of that engine. You're the best, Eric! Thank you for all you do.
