'86 faaast idle (sort of long) 200 1986

posted by  someone claiming to be rick245 on  Wed Jun 28 14:58 CST 2006 [RELATED]

I bought an '86 240 for my daughter. It idles at about 2000 rpm. The previous owner had taken it to a shop who replace some piece of wire between the throttle position switch and the air idle motor because they said it was faulty and when they did that the fast idle started. They told him then that the problem was a failed throttle position switch, air idle motor, and CPU and for some exhorbitant fee they would fix it. He took the car home and parked it.
I have replaced all the stuff they said it needed with junkyard parts as well as a new (used) engine wiring harness. I cleaned the throttle body and replaced the intake manifold gasket and throttle body gasket.
It still idles at about 2000 rpm. If I clamp off the hose from the idle motor to the intake bellows it idles at about 1200 rpm. Also the idle speed screw is completely closed.
What am I missing. Just replacing one wire shouldn't do this I wouldn't think and I put a new harness in. What am I missing? The car runs awesome otherwise. It is super smooth and quiet. Gas mileage seems normal.
Help??
I have 2 '83's and 2 '84's also so I'm no stranger to Volvos and their ways. I just can't figure this one out.
Thanks for all your help.
