I have a 2009 cheyenne single cab originally a 5.3 but i replaced it with a 6.2/6l80 with 4x4 transfer and front diff but engine power reduced message keeps coming up replaced acceleration pedal had it programmed and still keeps coming up. Any advice as to what it can be any ideas, thanks in advanced!!
Did you use the donor motor's computer or tune the factory computer for the swap?
REP mode triggers specific codes, what are they?
yes donors computer and it is tuned for what it has it has a couple bolt ons but at first it read the throttle body code had it cleaned with carb cleaner and worked for a while then happened again with the pedal sensor code this time, replaced it and worked for a while then happened again
I have a used TAC module from an 04 tahoe ill sell for $35. I also have a shaners ported throttle body i dont need. That would cover a possible bad TPS and still get more performance if it isnt the issue.
Also clean your grounds on the back of the driver's head and the block on the passenger side. Check the connection at the ring terminal on the back of the block on the pass side. The cable is known to break but the terminal holds in place because its crimped over the insulation. They are a **** to get to. There is also a ground on the frame below the driver's door. To check too.
