In a 2007 Chevy Tahoe, the idle air control valve can be found on the throttle body. This valve is responsible for managing the engine's idle speed by adjusting the airflow when the engine is not in use. Its internal coil controls the airflow by opening and closing. When the engine is cold, the IAC valve assists in starting it. If it malfunctions or breaks, you will need to have it replaced, which can cost anywhere from $120 to $500 on average. Labor costs typically run around $70, with parts ranging from $50 to a little over $400.
