- Irregular idle speed. One of the most common symptoms associated with a problematic idle air control valve is irregular idle speed.
- Check Engine Light comes on.
- Engine stalling.
How do you check a bad IAC valve?
Here is how to test and clean the valve:
- 1) Open the hood of your vehicle.
- 2) Pull the electrical plug off the control valve.
- 3) Take out the idle control valve and flip it over.
- 4) Take your voltmeter and set it to “Ohms.”
What are the signs of a bad idle air control valve?
Common signs include irregular or unusually high idle speed, the Check Engine Light coming on, and stalling while idling.
What causes erratic idle?

Why is my car idle pulsing?

What does car surging mean?
