What can cause high idle problems?
The most common problem is a faulty fuse. In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. This can be impacted by bad fuses in many different electronic systems in your car. Next, your high idling could be caused by a computer malfunction. via
Where is the intake air control valve?
The idle air control (IAC) valve is located on the throttle body of fuel-injected engines, where it works with the vehicle's ECU to electrically regulate airflow to the engine to ensure smooth idling. via
How do I reset my idle air control valve?

What should IAC be at idle?
The typical consumer car will idle somewhere in the range of 500-1000 RPM, depending on the vehicle. Consult your owner's manual to find your specific car's normal speed. High-strung performance cars may have higher idles, and motorcycles have idles that range between 2,500-4,000 RPM. via
How much does it cost to replace an idle air control valve?
The replacement cost of an idle control valve is anywhere from $120 to $500. The cost of the parts alone will be between $70 and $400+, depending on the make and model of your vehicle.

How do I adjust the idle RPM?
Turn the idle screw, now exposed from the protective rubber coating, in order to adjust the idle. Loosen the screw in a counter-clockwise fashion to increase idle speed or tighten it in a clockwise manner in order to decrease the idle speed. Ideally, you will want the idle to rest at 650 RPM. via
