Hey guys I need some help. Car is a 94 GT with Strim 42lbs injectors 70mm bbk tbody. For some reason the IAC was unplugged and the car was idling 750-800rpm, then I reset the computer and plugged the IAC in and now it idles at 1000 rpm. The idle is much more stable if I leave it plugged in.

Should I leave it plugged in or out, oh yeah the computer is chipped by alternative auto.

thanks
