Bother to take off the ivac and clean it out?
Check vacumm leak with brake cleaner(hear idle surge when leak is found)
Check pcv valve for proper operation..
Throttle body working properly, no carbon build up on plate
Just a few things to look at

I don't have my voltmeter down here and i will check the idle adjustment after I reinstall my fuel pressure regulator. I didn't clean the IACV because I've heard it was complicated and didn't want to open it up if it was functioning well as well as me not having the gasket for it. I also couldn't find any vacuum leak. PCV valve is 2 months old, throttle body was cleaned prior to reinstallation.
I'll check out the MAF when I get my voltmeter down here and if i cant figure it out I'll take off the IACV and thoroughly clean it. I've heard that feeding it fuel injector cleaner can clean it well but i fear hydrolocking the motor. I have about 500$ left to make it reliable again as I'm not working at the moment but worst comes to worst I can afford an IACV as well as a MAF. Think it could be the ECU or wiring?
