Idle Question

When I start my SC after it's been sitting, like all night or all day, if I don't blip the gas pedal once, it idles very roughly. And it will idle with a bad case of the shakes until I blip the gas once. If I hit the gas pedal once, just a blip, before I turn the key or as I turn the key, it starts and idles fine. What the heck is going on?

Sounds like a sticky or bad IAC. It is located on the side of your TB.

Only FORD has the correct IAC that will fit the SC. All the aftermarket IAC WILL NOT FIT! Good Luck!
