if the iacv is working, when disconnecting it the rpms should drop right?? if they drop this means that the iacv is working. if the iacv is disconnected and the rpms do not drop then this means that iacv is bad then, right??...correct me if im wrong.

i already tried that. well i tried this......."Next cover both holes up with your fingers. The car should sputter and die (or almost die). If it does then the source of your crappy idle is the IACV. Replace it. "

the thing is that on my jdm h22 throttle body, i only have one of the two holes. the top one. im guessing that's my iacv. does this mean that im missing the fitv??

 

can he run his codes?
