Ok, I finally fixed my idle problem with a new temp sensor, new fuel injection relay, new radio supression relay, new power stage and other numerous things. I have 173,000 miles on my 1993 940T wagon. But now I have one remaining issues which is caused by the clutch on the A/C compressor. everytime it cycles on and off, it jerks and the idles spikes. I hear a squeal everytime it cylces. I just replaced the belts. Is the refrigerant low? Bearing bad? switch? This car is becoming a high maintenance woman! :)

There may be a problem within the compressor itself. You might try removing the belt, then energize the clutch and grab the pulley and see how hard it is to turn the compressor. It shouldn't be TOO terribly hard to turn.
