The idle air control (IAC) motor is used to electrically control the amount of air that enters the engine while at idle. When the fail they can stick open (retracted) and allow too much air to pass causing a fast idle, or they can stick closed (extended) and not allow enough air to the engine and choke the engine. Normally, a good throttle body cleaning will involve removing the TB and cleaning all passages as well as cleaning the build-up from the IAC.
