    Check fuel pressure and do a tune up.

    check timing as well.
    And check the erratic idle article if you got a problem with that as well.

    Just to let ya know i had the same problem except mine was going down to like 200rpm and 100rpm sometimes but it never stalled. It always freaked me out cuz it could of stalled anytime it wanted. I was running a crappy chipped p28 ecu and the problem started to go away after i changed my computer back to the stock B16 Sir II ecu. Check your plugs as well cuz in my case the p28 ecu did a number on my spark plugs cuz it was running extremelly rich. Does ur car run rich by any chance?

    timing is good and i dont think it can be fuel pressure. i think its the iacv or the tps

    Why did you rule fuel pressure out?
    Try IACV... and adjust the idle screw you're not supposed to adjust?

    IACV is good and running... dunno if fuel pressure but i dont think it could be that. but also what my engine does is suck gas up like a vacuum cleaner.
