I have a 1994 Toyota Celica ST Coupe 1.8. When you let it sit and idle it misses a little bit, and is idling higher than normal, When goin dwn the road and push in the clutch and coast the rpm bounces but stops when you come to a complete stop. Sometime feels when you let off the cas instead of having some back pressure its as if I had the pedal in just enough. And it all started this at the same time.

Do you have a check engine light on and when was the last tune-up?

Engine running rough or misfiring can be cause by the following:
