Idle air control valve (IAC) is on the side of the inlet manifold on top of the engine.

Symes may have the answer, the alternator is almost at the bottom of the engine. :y

It's not idling rough

Mine wasnt either but the computer picked up that the coil was on its way out. I would try it , cost nothing and takes 2 sec...who knows!?
