The pot metal in the AAR's is finally starting to warp with age these days, and if its not just plain gunk it might be the warpage that is binding the shaft... Id take it apart and clean it up and if that doesn't work shave a little off were its binding.

When I ran the engine most recently, I plugged up the AAR except for a tiny opening, and the idle slowed down but the car did not seem to want to stall. Before, when I ran the car for 20 minutes, there was no change in idle speed due to the AAR closing, and there was still a very strong vacuum in the AAR hose. I put an ohmmeter to it, I got a reading of 14 ohms between the wire and the body of the device. There's other tests I'd like to perform, such as applying 12V to it on a bench and seeing if the rotary valve turns. Since I have an automatic, it doesn't seem like I can realistically open this one up and see if I can free it inside.
