Idle speed is controlled by the computer via the Idle Air Control (IAC) valve. A dirty or sticking IAC valve, or a problem in its control circuit, can cause abnormal idle speeds.

Without knowing more about your vehicle, such as mileage, engine option, and maintenance history it’s hard to say much more.
