idle problems, hard start. 700 1991

You need to test it in the manner Bruce describes. Use a pair of pliers or such while car is running and squeeze off the tube the supplies make up air from the iac. There should be a marked drop in idle speed. I would add, when the car seems to be idling low, strike the body of the IAC with a couple sharp raps from a metallic object(like a small wrench). If the sharp raps bump the idle up, IAC is failing.
