Stuck throttle cable maybe?
Lately in the cold I've had like 3 scary instances where I'll be driving and the car will just start gunning it full speed on its own, I have to slam the brakes also to the point of ABS to slow it down, if I take if out of gear it would blow up because it would easily bounce it off the rev limiter. Normally I wouldnt mind this but today it did it to me in the middle of traffic and I also plowed a guy at 45, I couldnt do anything to stop it but ride the brakes, I didn't try and unstick the pedal (if thats what it was) because it would rev it even higher. I turned the car off and it continued to do it,even after pumping the gas pedal with the engine off, as soon as I turned engine on again it revved. Could this be a stuck cable or a IAC problem? Any suggestions from Lucky or someone?
