One problem related to accelerator pedal sensor has been reported for the 2004 Chevrolet Suburban. The most recently reported issues are listed below.
Driving down the road, when all of a sudden "reduced engine power". Replaced the throttle body, pedal sensor, and wiring harness without any success. Gm wants 150 just to plug it into their computer to tell me what I can get down for free with my buddies code reader. . . . No I won't let my wife or children drive the car. I only drive it to and from work. Had to go out and buy a Toyota just to keep my mind at ease so my wife and or kids won't get killed from this problem. It seems like chevy/GMC doesn't care about this issue until multiple people die from this. I hope to see that they will do the right thing. Thinking of contacting my congress representative to see what they can do to help out us that are dealing with this issue. Nobody else is.
