Hey guys,

I need some insight on what might be going on with my 93'. First of all the fuel system is stock, the motor has been rebuilt about 8k miles ago. I also have a power fc which I adjusted the idle to 850-900. Relearned the idle as well. I have checked my tps and it's in range and my iacv has been changed out and checked.

Basically on cold starts sometimes the idle would not stay consistent and when it's still cold and I come to a stop the idle will dip all the way down to where the car stalls.

When the car is warm though it's totally normal, idles fine, catches fine. What could be the issue? Injectors? Any info would be appreciated.

Thanks in advance.

Dan.
