Hello everybody,
So, vacuum leak...

What i've done:
-Replaces upper/lower intake gaskets three times
- plugged in o2 sensor that was unplugged...(CEL OFF permanently since i plugged this in.. still stalls)

I think it is a simple idle problem but i wouldn't really know.. i think this because:
-AC (when on)keeps car from stalling when i come to a stop
-If i am gentle, and give it some gas at a stop, idle balances out
-If i come to a harder stop, engine tends to stall
- Seems to want to stall more under hot conditions
-CEL OFF since plugged in 02 sensor, had been on for months before that

What do you guys make of this? Is it a small idle problem, or something else?

Try cleaning or replacing the IAC valve. Insure none of the vacuum lines have cracks. I replaced all mine as they cost little. How is the PCV line and valve? It is a natorious culprit for cracking.

I will do all the IAC stuff, i actually have a pcv valve i can replace the old one with. I'll try that out. I really hope it's something that simple. Thanks for your help
