Ok heres the thing. I own a b20b and trying to get the idle steady. I have checked for vac. leaks(spraying carb cleaner) switched out IACV, adjusted valves. Any idea what it could be? The idle surges when i give it some go juice and hold it, it sounds as if it is missing. Ive also checked the timing but with it surging its hard to get it just right.

?????? Please Help!!

 

i heard of this same thing on antoher forum, ill see if i can find the thread

Clean fitv its under ur throttle body. Take it off open it up and tighten the white plastic screw in side and clean with parts cleaner. Should fix ur problem. Search how to clean fitv
