Hello, I have a 2000 Silverado 2500 with the LQ4. I have attached a pdf with all of my trouble codes. I was wondering if anyone had any experience with similar issues. The instrument cluster works but the oil gauge is a little jittery, I replaced the sending unit and it’s still the same. It has a rough idle and I tested for vacuum leaks, didn’t have any. I replaced the fuel regulating valve because the was fuel in the vacuum tube, still has a rough idle. The brake ABS light is also on. Could this be a problem with the ECM? S3.pdf

Hello, on my 2000 Silverado 2500 with the 6.0, I am getting the service 4wd message. It happens while driving in 2wd or when I shift to 4 auto, 4 hi or lo. The fact that the light comes on after a few minutes of driving in 2wd is kind of confusing. I know the 4wd engages because when I put it in hi lo, it’s nearly impossible to turn the wheel. All help is greatly appreciated. edit: I also get the p2700 engine code which my reader says is the trans friction element but I don’t see much online about that code. Transmission appears to shift alright. I have attached screenshots of all of my trouble codes.
