Idle Air Control Valve
Installing / Replacing the Idle Air Control valve (IAC)
The Idle Air Control (IAC) valve is controlled by the ECM and tailors airflow to help
maintain a set point speed at idle. The behavior of the valve can be calibrated for your
combination through the laptop Pro Tuner software. The IAC comes installed on your
system throttle body. Replacement of the valve is through removal of the 2 mounting
screws, remove old valve, replace gasket, and install new valve.
