Extremely low idle, running rich, CEL.. help please

[Boostit]

I did do a search, just wasn't sure what exactly to put in.. so i didn't get any answers back that i needed.

I do not have a data logger(yet) or obdII scanner so i need help diagnosing this problem. I am throwing a CEL to begin with. I had been for a little bit, but i just got the car back from getting the head rebuilt so i haven't had the chance to fix alot yet. Basically, my car idles at 200rpm now. It hit fuel cut once(i didn't take it up again cause it scared the shit outta me) at 12lbs boost, i hadn't even reached 15lbs. You can smell the fuel at idle, like she is trying to flood out. When i turn on my a/c my car idles at 900rpms, but the moment i turn it off, it'll drop right back down to 200rpms and it struggles around there to stay alive.

I have unplugged my battery twice to see if i can reset the CEL but it comes back on about 20 minutes after or when i get around 5lbs boost(whichever comes first).

I am thinking it's my o2 sensor gone bad, but i can't be sure. Suggestions?

If you cant find anyone with a Pocketlogger, then go to Auto Zone if they have one in your area. They will pull your codes for free. I don't really think you can do alot of problem solving on this until you get the codes, then should be able to fix it.

Good Luck!

Try to get the CEL pulled, but for a quick stab I would say it is your ISC motor.
