I drove the car home about 90 min and when i start it up the idle doesnt drop below 2000. I was using the cruise control on the way home dont know if it is still holding the throttle open or something stupid like that. I was drivin for a while and when i slowed down to make a turn and pushed in the clutch the rpms stayed at 3000. so i shut the car off and started it back up and it was fine. I didnt use the cruise anymore after that and now its still running funky. Any ideas????
