ABOUT YOUR VEHICLE’S IDEAL AIR CONTROL (IAC) VALVE

The Idle Air Control (IAC) valve is a crucial component in modern automotive engines. It regulates the amount of air that bypasses the throttle plate, allowing the engine to maintain a consistent idle speed, especially when loads fluctuate. The valve adjusts based on various factors like engine temperature, air conditioning use, and electrical load to prevent stalling and ensure smooth operation. If faulty, symptoms may include erratic idle speeds, stalling, or poor engine performance. Regular maintenance and occasional cleaning can help prolong its lifespan and ensure optimal engine performance.

Common Failure Symptoms

• Stalling when the engine is idling
• Rough or unsteady idling
• Extreme RPM drops during a slowdown
• The engine may shut off if the AC is turned on
• Check Engine Light is on

Common Causes of Failures

• General solenoid failure from everyday use
• Wear and tear from corrosion
• Clogged valve

COMMON QUESTIONS

Why is my Holden Commodore stalling when I stop at a red light?

A failing IAC valve cannot bypass enough air to maintain engine idle when the throttle is closed. This results in rough idling RPM drops and stalling when stopping or turning on the air conditioning.

Does this fit both the Buick V6 and the Ecotec V6?

Yes. This IAC valve is compatible with both the early 3.8L Buick V6 (VN-VR) and the later 3.8L Ecotec V6 (VS). It also fits the 5.0L Holden V8 engines from the same era.

Does this require programming after installation?

No programming is required. However it is recommended to disconnect the battery during installation so the ECU can reset and learn the new idle parameters once started.
