Smooth out a rough, hunting idle with the Standard Ignition Idle Air Control Valve AC286. It drops in as a direct-fit replacement for the 1999-2000 Ford Windstar, metering the amount of air that bypasses the closed throttle plate so the engine's control module can hold a steady idle speed during warm-up, at stops, and under changing electrical and mechanical loads.
If a failed idle air control valve is the cause of your idle trouble, this AC286 replaces it and restores the intended bypass-air path.
