I have a similar problem with my 2004 silverado, it goes into reduced power mode, I took it to chevy and they replaced the throttle body and power harness, 4 weeks later it started doing it again but I didn't take it back because the dealership charged me 1100 dollars and I wasn't paying again so I checked the harness myself. each time it goes into reduced power mode I move the connection to the throttle body, reset the truck with my scanner and I am good for another few weeks. try checking the harness connection to the throttle body

I can answer most questions concerning 4X4 engine, drive line, suspension, electrical, and fuel, both diesel and gasoline. Ford, GM, and Dodge, old and new.


I have been maintaining a fleet of approximately 55 light, medium and heavy vehicles for over 20 years. Most are 4X4 pickups and off road fire fighting trucks.
