Is it on the original throttle actuator? If yes, get it rebuilt.

Mine too, but not all the time. When it is cold (first started) it is very very responsive and the pedal is like a hair trigger. As soon as it warms up and the upshift delay goes off, it is like an old Buick. (not that there's anything wrong with Buicks). Before the major tune-up, caps, rotors, wires, coils, fpr, fuel filter, it was fine cold but horrible when it warmed up, like I had to put it in Neutral at red lights so it wouldn't conk out. I am rebuilding my engine wire harness and ETA harness right now.
