Hello fish-- There's a lot of things that it could be. You don't sound like you plan on fixing it yourself, so bring it to the best mechanic you know of. I would guess it might be either the Idle Speed Control Actuator or the Throttle Position Sensor. That is the best diagnosis that I can give you without actually seeing it. Let me know what you find. Good luck from Bovan.
