Rough idle

[ThunderChicken001]

Hi, i own a 92SC and for about a year now its been idling rough, to the point of almost stalling sometimes.

It will stall out if u turn the wheel at a stand still, but well driving runs good. When cold idles fine, when put into gear will choke a lil before coming back to a normal idle.

Anyone Have any idea whats wrong?

Sounds like your IAC valve is bad (Idle Air Control valve).
Try unplugging it when car is idling. If the engine stalls, it is probably OK. If the engine keeps running with no change, most likely it is bad.
Good Luck.
