My '94 SC auto starts OK and idles at about 1200 RPM for about 20-30 seconds. Then it slowly goes down to about 800 RPM and idles a little rough. I shift into drive with the brake on and the A/C on and it goes down to about 650 RPM. It damn near shakes the radar detector off the windshield. It accelerates fine and runs fine above idle. The in gear, A/C on and brake on idle just sucks! I have 94K on the SC and replaced the IAC at 73K. Also, when I pull the connector off the IAC it makes no difference in the idle. Anybody have any data on the average life of an IAC? How long do these things last? After reading some other posts I guess I screwed up buy trying to clean it with carb cleaner although it is no better or worse. This rough idle problem is a pain in the donkey. Any ideas or help would be appreciated!
