All right so here the deal... i have a 94 delsol B16. the problem is that when i rev the car around 1500 RPM the rev drops and goes back up, before the car use to stall untill it warmed up. so I took the IACV out and cleaned it an it doesn't it will stay on with out me having to give warm up and stay on the thottle. but the rev thing is starting to drive me nut. a machanic that i just have to calibrate my IACV, but i don't know how to do that, others say it's my FITV, and another person told that my IACV is bad altogether... I'm not sure which way to go on this one and i don't want to have to buy a new IACV if it something else altogether. so let me know what you think...

 

take your fitv off ur car...dissasemble the cover and screw the white peice all the way down. see if that helps...it gets loose over time and creates a vacuum leak.


cheers
