reduced engine power
code p1514 and c1278 are coming up. this car was wrecked hit on the computer and cut the harness. have replaced everything, gas pedal, computer, throttle computer, wireing harness, abs pump and controll module for it, throttle positioning sensor. only thing i can think of is the throttle body with the motor thing on the left side of it that opens the throttle blade. care runs fine everything works untill you snap the throttle. if you excelorate slowly it is fine, but if you push down as to pass someone then reduced engine power with the above codes. stop the car and turn it off and restart it is fine untill another snap of the throttle. any help please! thanks greg

Reduced power
The only thing left in the system is the throttle body. I too went through a similar problem, replaced the TAC and the "gas" pedal and it fixed it. There is nothing like passing a truck and having the engine power go away! Puckerville!
