Usually a bad or failing idle control valve will produce a few symptoms that can alert the driver of a potential issue.
- 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?
Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.
Can you clean an IAC valve?

Why is my car idle pulsing?
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
What does car surging mean?
Surging or misfiring Engine surging is when an engine starts easily and accelerates smoothly, however after a few minutes at a steady speed, it either surges in speed or misfires. Misfiring happens when one of the cylinders of an engine’s combustion cycle fails.
