my gsr is idling from about 1- 2k. i changed the fitv which i was told needed to be replaced but it still idles very rough when its around 1k and it jumps around? is this distributor or throttle cable or iacv problem? i dont wanna buy stuff if they arent broken and the iacv cost like 200 bucks. could anyone give some more input into this? thanks

 

bump

 

any mods?

 

has a skunk2 im and type r throttle body and i/e/h/ flywheel and clutch

 

could be 1 of several things.
try checking for a vacuum leak, iacv, possible bad map.,or ect

just read that u wanted to be sure about what was wrong, the only was to be sure is to hook a scan tool up to the car

 

Try your TPS SENSOR, or see if you have a leak around your throttle body or intake manifold, i had the same problem with the idle and finally figured out it was the a leak from the throttle body

 

well put a new gasket on the throttle body and now im thinking of checking the iacv? anyone know what to clean these with? all i got is superclean right now but i was thinking of trying to clean it to see if that helps. anyone know if thats alright to clean it with?
