KJ,
Well, this is the first time I heard the AAR referred as Fast Idle Valve. The AAR causes high cold idle because the metered air is by-passed directly above the throttle body. And the slide valve inside the AAR gradually closes as the heater heats up the bimetallic spring till fully closed. FIV (fast idle valve) is probably a good synonym for AAR.
