Where is the iac valve on a 2005 Ford Mustang?
The IAC (Idle Air Control) valve on a 2005 Ford Mustang is located on the throttle body. To be more precise, it's on the side of the throttle body, usually towards the front (closest to the radiator). It's a small, usually black, electrically controlled valve. You'll likely need to remove some air intake components to see it clearly.
