My car had a strange sticking throttle issue. It only sticks when fully closed, and only when returned to closed rapidly. If I jump off the throttle, it takes quite a bit of pressure to get the pedal to budge, then it's fine. It also only happens when the engine is running, and is 100% repeatable. If I ease off, it doesn't stick. The cables and throttle body itself appear to opperate smoothly. I'm thinking it's related to the cruise control. The sticking doesn't feel like mechanical binding, it feels like vacuum is working against the pedal. Any ideas?
