I agree with Merlin. The items on his list need to be checked and eliminated from the equation. I also have some input as to the idle air control, it is usually quite robust on that car and I have not seen them fail, however, diagnosis of that system would start with checking for power at the IAC valve/connector and resistance at the IAC valve. With the key on and the engine off, the valve should be felt to vibrate, if not, you have a problem with the IAC, let us know what you come up against mate.
