Preface (yes I've used the search button): I've spent hours searching multiple forums including this one and to no avail as I haven't fixed my problem yet.
Where to start with this one; well the car runs like complete dog shit on a cold start. Barely maintains any idle and will stall after any load for about a minute or two until the FITV kicks and and raises the idle. After that first initial warmup the car runs like a champ and has no stalling/idling issues. I swapped an H23 manifold onto the stock f22a1 and about a month or two after, and in the winter this shit started to happen.
I have:
1)Cleaned and replaced 3 different FITV's (even boiled one and adjusted it, apparently that didnt work at all )
2) Replaced the IAC multiple times (junkyard pick, but tested to make sure proper operation before install)
3) Changed ECT Sensor, IAT sensor, MAP Sensor broke out the trusty multimeter and checked resistances.
4) No vacuum leaks to speak of, hoses are ran correctly.
5) Deleted the Air Boost Valve (fixed a nasty driveability problem, but not start up.)
6) In my desperation I even swapped in a random ECU I had laying around.
Can anybody tell me what I'm missing or need to look at, I've turned wrenches (professionally and on the side) for years but this thing is confusing the hell out of me.
