iac valve question
just trying to figure what the iac valve does and do I need it? my problem is the idle speed won't come down to 800 while the car is still moving, like when coasting down hill in neutral, I have to come to a complete stop before the idle drops down.
Also I have little or no compression braking for the same reason. I want the idle speed to drop quicker when changing gears, when I push the clutch pedal in.
thanks.

This is a very common mustang issue/design flaw. I don't know exactly how the iac works, but I highly recommend doing the iac gasket mod shown in the tutorials section in this forum. I did it and it truly transformed how my car drove! Rpms drop quickly when shifting and there is way more engine braking now.
