While going up a hill I had the cruise on and lost power. The reduced engine light came on and the cruise has quit. I pulled over and turned off the motor and restarted and the the was out but the cruise still didnt work and then the light came back on after a couple of miles. It comes on everyday and most times if I run the air conditioner it sputters. I have learned to deal with the service engine light but I dont know what to do about the reduced engine power and the cruise.
My check engine light and reduced engine power lights are on and the cruise quit on 2002 Chevrolet Trailblazer

you have a failure in the fly by wire system. you need as shop to diag it for you and give you a bid. it is not cheap. the throttle body is about 800-1000 just for the part. Roy
