92 V6 3.1L Dies, Won't Idle

It has gotten much worse and now dies whenever you let the it drop to idle with the clutch in and your foot off the gas pedal.. Always after it has warmed
up for about 10 miles..
Ok, so here is what I have tried...
The electronic module failed six months ago and was replaced so don't think that is it.
I replaced the exhaust including the cat converter on back.. Did not fix it..
Pulled the IAC out and cleaned it.. Reset the ECM as described in several areas... No luck... Doesn't mean the IAC isn't bad but it didn't improve it at all.. I notice turning the key on the IAC plunger doesn't move but turning the key off causes it to extended.. Should you see it move both directions..??..

does the check engine light come on?
first thing to do is see if what your ecm says take a paer clip and unfold it with the engine and key off insert the paper clip to the aldl port it should be under the steering wheel it is a square port the top row the last two connectors the ones near the passenger side of the car put the paper clip in those two connectors turn the key on watch the flashes from your check engine light it should flash 1 then flash 2 and repeat three times the it will flash other codes write all these down till it gets back to the 1 2 code it flashes all codes three times each post them here and I will tell you what the book says
now here's an uneducated guess
I would check the egr 1st and double check your vacume lines

No, I don't get any check engine light. I do have a code reader and have verified no codes. I worked on it last night unplugging and replugging the IAC and MAP connectors. Now it seems to work again and the radio static I mentioned in my other message seems to be gone...^(*^&$^&@## frustrating....
