Sometimes it'll stall without putting it in drive. I can pull each plug wire off one at a time and it stalls,which makes me think each plug is firing. I recently replaced the coil. I cleaned the portal for the IAC and even replace the IAC. No change. This is a 4.3 V6 engine.

Check for vacuum leak(s) more likely EGR valve is stuck open!!!! Tap it with a wrench, or such, to see if that helps.

Problem solved. I can tell you a lot of things it is not (because I replaced some parts). The real problem that fixed it was the IGN Module inside the base of the dist. Thanks for the suggestions. Cliff.
