all good things to check. I also had erratic idle due to the throttle plate not seating correctly because of a weak spring.
You have identified a problem though, the aux air valve has two wires that supply 12vdc only
when the engine is running. Did you test for voltage at the aux air valve connector in this condition? If so, we need to know what voltage leg is missing. With the engine running, grab a voltmeter and ground one meter lead probe on the negative battery post. With the other meter lead, probe one of the two aux air valve pins. One of those pins should yield 12vdc. If so, carry on with the next test. Put one meter lead on the positive battery post. Then put the other meter lead on either pin of the aux air valve. You should see 12vdc. Depending which voltage you are missing will tell us which way to trace this fault.
Yes I did check for voltage with the engine running. Nothing at the pins. I did try the ground to battery and positive to battery. No voltage ant the connector.
The loom looks fine and haven't seen any evidence of wire damage.
Next will be to test resistance to the wires. Where does the AAR power come from?

BTW: driving the car with out the AAR installed (Plugged the lines) and it seems to run pretty darn good with out it !
