hey, after installing my iceman CAI, my idle is very low at 200. its supposed to be 600-900. my car is a 95 civic ex coupe. how do i fix this?

 

reset the ECU. if it is still low then you might have to adjust your idle.

alot of people have lots of idle problems on this board including me. there are many many many.......many threads concerning this issue. if you search you will find everything you need to know.

 

yeah i had this problem after i rebuilt my motor. it was around 300 and was pretty rough, i raised it to 900 and it runs so smooth i forget the car is running sometimes! anyway, im not too much of a mechanic, but on the throttle-body there is a piece that rotates (it has a metal chain stuck to it) and basically when you rev it will rotate. if you aren't sure what im talking about, look at the throttle-body for moving pieces while someone revs your car. anyway, look at where it drops to at idle.. there should be a screw that it is sitting on. raising that up wil lraise your idle. careful though, a few turns and i had a 3,000rpm idle. also, make sure its tight because when the car gets hot the screw will get loose. mine didnt have a washer so i torqued it a bunch. you'll need a 7mm wrench (socket) and a two and a half allen wrench. hope that helps.

 

Not to **** on your parade, but it sounds like you adjusted the Throttle Body Stop Screw...which is preset from the factory, and should not be touched, ESPECIALLY for adjusting the idle.

There should have been another screw on your throttle body, the Idle Air Bypass Screw. Its this screw that allows additional air around the throttle blade to set what is called the Base Idle (which is different from the Curb Idle, which is the idle that is obtained from having the 2-wire IACV plugged IN).

Messing with the Throttle Stop screw will also mess with the TPS output. The TPS should sit at about .5V, +/- .05V (or 10% with a scan tool).

If you've adjusted this screw to any great degree, your ECU will not be able to bring the idle down...and pretty soon you'll be asking us why your idle is now HUNTING from like 900 - 1700 rpm.

Adjusting the Idle is outlined in the Helms manual.
