Hi there. Check the idle air control valve (IAC) on your vehicle. This valve is what controls the idle and is most likely stuck or has failed. When turning off the vehicle and then turning it back on, the valve will reset its self to normal settings. Replace the valve if you find that its not responding. If you need further assistance with diagnosing the idle air control valve on your vehicle, then seek out a professional, such as one from Your Mechanic, to help you.
