This could possibly be an iac or idle air control valve issue. the iac valve controls the amount of air that bypasses the throttle body in order to maintain proper idle, and is mounted on or very near the throttle body on the intake manifold. check the connector to ensure it's tight and the connections are clean, not corroded. i'd recommend replacing the iac valve.
