The fuel injected Mustang uses a small motor/valve assembly that allows a specific amount of air to enter the engine to control it's idle. This valve is comonly called the idle motor, the IAC (idle air control) or the IAB (Idle air bypass). When your car is new the IAC works remarkably well.The problem arises when the car gets some miles on it (usually 75K+) and carbon fouling takes its toll.epending on the year of your Mustang the IAC can be in a few different locations. - On 5.0L Fox body cars the IAC is bolted to the side of the throttle body. - On SN-95 cars it is bolted to the intake manifold. - On 4.6L DOHC and SOHC engines the IAC is located on the upper intake manifold.
