It will be your Idle set screw or IACV. Clean the iACV and if that doesnt fix it then reset the idle. Make it slightly higher. Also clean the FITV.

ha bud i told you the other day to clean the idle air control valve and then maybe look into cleaning the fast idle thermo valve. is that b20v really not running right again?? good luck man hope it gets fixed quick

Ha it runs as long as you keep it revved to 2k. Once it warms up though it will idle perfectly fine. You saw how different the idle becomes once it goes from cold (1.5-2k rpm) then 1k when warmed up.

that sounds like the fast idle thermal valve then.

mines is the complete opposite it revs up to bout 1k until its warmed up then drops as low as 200...i haven't touch the idle screw as yet cuz my knock sensor isn't in its still on the other block, im thinking thats wat causing the low idle "i cud be dead wrong" but i dont want to meddle with any thing until thats in...
