On a 1998 Chevrolet Cavalier, the idle air control (IAC) sensor is located on the throttle body, which is situated on the intake manifold. You'll typically find it on the side of the throttle body, connected by two screws and an electrical connector. To access it, you may need to remove the air intake duct and any other components obstructing your view. Always ensure the engine is off and cooled down before attempting any repairs.
