IACV - Decel (like hitting the brakes)

The IAC also has a lot of control over how the car decelerates. If you disconnect the IAC, the engine braking is much more. You let off the throttle, and it is like you hit the brakes. This is because the IAC is not allowing any air at all into the engine and it would prefer to stop.
