[jwheelz1212]

mostly stock 86 gn, hot ire kit, vacuum breaks, ta49, pypes exhaust, thats mostly it. its running rich, the hot idle is too low and cold idle is to high. was driving down the street and it just stalled on me wouldn't start so i let it sit for 5 minutes got in it and it started right up and sounded good. hasent stalled on me again but sputters when i get on it a little bit. my dad said it could be the IAC. looking for your guys input

car is still not running right anyone else have any ideas?

What is the condition of the ignition system, and what is the plug gap?
What chip/injectors/FP?

You are not going to get much help without your ability to post some data from a scantool like scanmaster. :frown:

Sounds like a test is needed of the coil pack & ing module.

Coil pack or ICM

Swap the ign mod/coil pack with a know good one, pull plugs and if any doubt replace them.

With a scanmaster you can adjust and reset your IAC

OP;
You can also reset the IAC w/o a scantool. It's a pain but can be done.
