My car idles kinda high and low then sometimes bogs down and dies... someone did a diagnostic check on my car and said the um Idle Air Control Valve was bad... so i bought a KEM IAC and installed it... then the car idles at like 2000RPM... had to reinstall back old one temporarily... could it be the KEM one causing the probs and that i should get the motorcraft one?
 
Yes. Most of the aftermarket IACs don't work on the SC because they have to be mounted backwards and the oil filler tube prevents that. Only the Motorcraft part, or an IAC which is normally valve closed, will work.

I had the same experience. Tried an aftermarket IAC, and the engine raced.
