My buddy?s 05 gto keeps going into safety mode and i believe it?s because of a correlation issue between the throttle body and the accel pedal. The accel pedal percent keeps glitching between 0-10% really fast, like a flicker, even when the pedal is being left alone.
The throttle body at idle sits at about 10-12 percent open give or take, and i?m sure this is due to it idling and obviously if it was all the way shut it wouldn?t run.
What i don?t understand is why when giving it half throttle or even wide open, the accel pedal doesn?t eventually cross paths with the percent of the throttle body, and then they both are relatively the same percent? the throttle will be maxed out at 90 percent, while the pedal sits at around 70-80. i believe the computer is seeing this and thinking it?s a hung throttle or something and going into safety mode.
The throttle body and pedal have both been replaced, as well as a new alternator if that means anything to you.
Drive by wire throttle body as well.
