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.

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.

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.

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.

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

[@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.

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.

[@benjamincresswell3713]

In 1978 I put Mobil 1 oil in my Dads Olds Cutlass at his new house. My youngest sister scratched her name and the year in the cement garage floor when they poured it, that's how I know what year it was. The Mobil 1 oil can said it was "guaranteed" for 25,000 miles. When I changed that oil my Dad said he was not comfortable going 25,000 miles on an oil change, so we adopted a 10,000 mile interval. Mobil 1 wasn't brand new brand new, but it was relatively new on the market so I didn't know anyone using it. We felt like pioneers using it. Today I have a 1998 GMC Yukon with 325,000 miles on it, and I have always put Mobil 1 oil in it at 10,000 mile intervals. Dad's Cutlass was a cast iron 350 Olds I have a cast iron Chevy 350 Vortec. Dad's car was Quadrajet carbureted I have Central Sequential Port Fuel Injection commonly called a "Spider." Neither one of the 2 engines used any oil to speak of at all. I do live in Southern Michigan and have to admit the salt ate Dad's Olds and my GMC is an eyesore, but they didn't use oil. We never ever added any between changes. I also have a 2017GMC 4.3L V-6 VVT GDI w/ AFM and it uses some oil between changes, but I go by the DIC when to change it, so I don't know how far it goes. I wonder why my newer truck uses oil. It's not leaving spots on the garage floor, so it must be going out the tailpipe. Why? And I wonder how much fuel we had in our iron 350's oil at 10,000 change intervals.

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.

Excellent Video, Thanks! I just use brake clean to clean the Maf sensors, never had a problem. I guess if I would make a video on it I would get MAF cleaner 🤣

I just picked up a 2008 LS Silverado, 1500, it has had its engine replaced the engine has about 60,000 miles than the overall vehicle has a little over 160. I love the way it drives but it keeps throwing an intermittent code and it finally went to a hard code where it was pushing a number to injector forced open, and an intermittent Miss on cylinder number 4. They are still trying to figure it out this the first Chevrolet I have owned ever, though I have worked on them, I have been impressed with the ls, every built a couple of them. I was surprised at how much they copied the big block Chrysler block design. But have, where's my research notice that these engines tend to sludge themselves up quite readily if they are not driven enough miles. And people have always had a tendency not to check the oil on them, so far this one is not using any oil to speak of. But when it's down on cylinders that sure is a pain in the ass to get to go anywhere and it doesn't shift worth a damn. Still getting used to it. The only observance I've made when I rebuilt these things as I have found more than a couple of them with ring gaps of 30 saw from the factory. There is no reason on this planet, with the number of years of people have had and Building engines have a .03 0 gap on a naturally-aspirated engine. That is just asking to drink oil. It is stupidly wide. It should be no more than .018
