my accellerator keeps sticking when i accellerate "aggressivly"N E ideas? on 1992 Cadillac Seville STS

I have to stomp on the accellerator very hard to get it to release. I thought a broken engine mount might be the problem but isn't.

An excessively dirty throttle body will cause a throttle to stick among other things. Have a reputable shop check out your car for you to determine the problem.
