The idle air control sensor regulates the amount of air that bypasses the throttle plate during idle situations and maintains a stable speed of your engine. If you experience rough idling or stalling, then you may have a problem with the IAC sensor. This can easily be located positioned on the intake manifold, on or near the throttle body.
