Technically, the AAR is a regulator whereas the AAV is a valve. As a regulator, the AAR modulates the amount of air to affect cold idle. The AAV, on the other hand, is purely emissions related IIRC and is either open or closed as any good valve should be (I can't remember it's function, as the '87 models don't have one for some reason).
These are two different animals from what I can remember reading. The abbreviations get swapped all the time. Someone else out there knows more about the AAV than I.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
