    Several possibilities; vacuum hose leak, air intake leak, maybe the throttle position sensor (TPS) or the idle air control (IAC) valve is faulty. Check the vacuum hoses and air intake as first step.

    Check out the many on-line auto parts sources; such as - or - to list just two sources - for the replacement parts, such as the IAC or TPS.
