Anybody got a list of things to check out to fix my random stalling problem. Its only when I let off the gas to go to a stop.

After installing my heads, I dont know why but the stalling has been bad, 2-5 times a day.
As well, the tip in stumble has gotten worse too. I'm running lubrants 110 chip, I didnt have too much trouble with it before.

Maybe more airflow with your heads ported? You may need to readjust your IAC and TPS. dunno Are scanmaster readings ok?

Yep, sounds like the IAC needs to be readjusted. Also I have heard of this when guys go to a little bitty converter, stalling after the burnout.

When I first bought my car, it kept stalling on the way home. Come to find out the AFPR was set at 52psi with the hose off.

Maybe just try a new chip.. what are you running now?

I'm running lubrants 110. The only place that chip works well is WOT, Idles like a Chevy missing plug wires.

You guys were correct I did have a vacuum leek, and I do need to set the IAC, Its off.

Lubrant chips idle on the low side. Send it back and ask Joe to add 25-50 rpm's to the chip. Also make sure you have "antistall" also due to your converter. Make the adjustments posted above first.
