How to Adjust Idle Air Control (IAC) Valve

This video shows how to adjust an IAC valve.

- the IAC valve controls the idling rotational speed (RPM) of the engine.
- the idle should be at 900 rpm if the engine is warm.
- if the idle is too low, the engine may vibrate or stall and may not start.
- if the idle speed is too high, it consumes more fuel.
- if the car doesn't have an rpm gauge, you can just listen to the correct sound of the engine.
