I have a 2015 Chevy Silverado with a 6.2L. About 2 months ago I had bent a rod on Cylinder 4. I replaced all the rods, cleaned all the rockers, new lifters (even AFM), new gaskets, plugs, and plug wires. After the truck ran fine for about a week, then threw code P0106, which is a MAP sensor code. And for the life of me I couldn't get the code to stop showing up. If the code is deleted the truck runs perfectly fine for about 30 miles, then it throws the code and has a bogged down, flooded feeling. I've checked everything I can think of and don't know where to go next.
What I've checked:
Wiring Harness and Ground Connections
New MAP and cleaned MAF
Air intake gaskets and filter
Cleaned Throttle body
Checked Fuel Rails
Compression tests (all at spec or very close)
No leaks in intake
After I spent two weeks after work on this thing I decided to take to the shop, they tried a new computer, new sensors, and ran a cylinder leak down test. The truck still is not fixed but I brought it home today because they told me the only option was to send the heads in to be cleaned and new valves. Said the carbon build up was causing this issue but I'm confused as to how that would affect MAP sensor. Especially when compression tests are all right where they need to be. When I replaced the rods I even checked to make sure valves weren't stuck and didn't make contact with head of piston.
Anything help and am open to all options. My next step is to take a look at injectors and to replace/clean the valves myself.
hello gm-trucks commuinty i’m having issues with a smog readiness monitor not completing. any information on this issue would be greatly appreciated. my truck is a 2001 Chevy Silverado LS 1500 with a 5.3L v8 and it’s 4x2. all the readiness monitors complete except the secondary air system causing the truck to fail smog in california. i’ve heard the air pump turn on at cold starts and even replaced the passenger side check valve. also replaced the solenoid that sends vacuum. everything in the secondary air system seems to be operating properly but the monitor won’t complete. i’ve driven 100s of miles and done countless cold starts but no luck. even the smog referee said the system is working properly and i should just drive the truck more. anyone else experience this issue and what did you have to do to complete the monitor? there are no codes stored currently and the truck runs fine. thank you to anyone that helps
I have a 2022 trail boss lt that has about 6100 mile on it now. Bought it brand new in may 2022 and it seems like the drivers seat leans to the left towards the door. Almost feels like Im gonna fall out of it and no matter how I adjust it it seems the same. Visually it looks like it sits level and is fine. Is it possible something is broken inside like the frame? I would assume the frame would have to be sturdy. Is there any place that sell a better bottom cushion?
My l84 5.3 cracked some pistons now thinking of doing a light hone but wanted to know if it would even save the engine ? The scratches are pretty light my nail doesn’t get stuck but I do feel em. The pours on the other hand I’m not sure what could have caused those little things ?
Hello all, My Sway bar was hitting my CV axle, as the title says. So I crawled under some trucks at the dealer to see what stock trucks are like and it turns out that the new TB/AT4's have longer end links then my 2020 TB. The new end link has a 3 inch rod vs the 1-3/4 inch OE part.
The part number for the longer end link is P/N:85590925
