2003 Yukon Denali reduced engine power stability system disabled I have replaced the throttle body the harness the ground wire gas pedal and the sensor and it is still doing the same thing.. This is a serious and dangerous problem and General Motors takes no responsibility for their defective vechicles!! My vechicle is used for my 5 children and I'm now without a vechicle GM does not care about it's customers!! My dad was a engineer for General Motors for 30+ years and he's absolutely ashamed of that gm is not offering a fix!!! I refuse to take my truck to a rip off dealer 600$ for throttle body sorry I had mine replaced by a certified mechanic for 250$$$ after reading these forums I know better than to go to a dealer!! My mechanic is now going through all the wiring on this hunk of junk he has 43 wires left to test.. Keep everyone posted as to the findings but it appears nobody is finding an actual fix!! Sad to say I will now buy ford
