when the AAR is disconnected and ports plugged, the cold start idle is VERY slow....like a tractor idle or something. I have to bump the idle screw to get it to actually idle.

then it will idle warm at like 1500-1700 RPM...which is way too high.

AAR connected, the engine WONT stay running cold(have to rev to 3000 for 1-2 minutes to hold idle)....when warm, the idle is fine...something like normal.

Does the electrical portion of the AAR work?

The AAR provides the "fast idle" to the engine when its cold. Without it the car will not idle cold.

Inside is a bi-metallic element that moves a window blocking off the hole through the AAR. closed, the engine idles normally. Open it idles fast.

Around the bi-metallic element is an electric heater element that is powered by the ignition circuit.

If the window does not move, the AAR is bad and should be replaced.
