Have you tried cleaning the throttle body? The throttle body can get carboned up and stick. Once you have cleaned the throttle body, the battery needs to be disconnected and the brake pedal held down for 30 seconds to discharge any voltage. Once this has been done start the car and let it idle for 15 minutes to relearn the idle position. See it this corrects your idle concern, if not we can proceed further.
