David, Part of all trouble shooting techniques includes substitution of questionable parts with known working replacements. Yes; if you can substitute an idle speed motor you will be able to eliminate that item as a cause of your problem.

Sometimes it acts like the microswitch isn't engaging and will idle around 1300 Rpm's or so. The microswitch is properly adjusted and clicks everytime the pedal is down. If you rev the engine high and then let it come back down it will idle correctly around 800 Rpm's. I think the idle speed motor may be sticking. When I remove the connector from the idle speed motor nothing happens. Driving with it hooked up or disconnected makes no difference in the cars idling. Yes, the 3 adjustment screws on the intake are all the way in. I cleaned the motor contacts but still nothing. I know where a Volvo 760 is that has the same idle speed motor. I will take a trip out and get it if you think that is what it could be. Any ideas would be greatly appreciated.
