I have an 03 Z71 277,000 miles. best truck ever. Now I have an issue..... I have a reduced engine power message. Codes say its the TPS and APP sensor. I have replaced the Throttle body with the TPS sensor. The Accelerator sensor on the pedal. The wire harness from the pedal to the Control unit on the firewall, and the Unit on the firewall.
I have checked the wires near the TPS and they look, and feel OK. But I still have the problem. If I clear the codes I can start and drive between 2 and 10 mile before the issue appears again. (Truck has no codes if I clear them and then only Idle)
