i cant get it to go down anymore... warmed up it still idles at like 1700 its realy anoying... the ecu was throwning a map sensor code so i changed it now the cod is gone but still idleing high... i also cleaned out the scereen in the iacv and turned teh idle adjustment screw in all the way in, the throttle cable is not tight or anything i even took it off the bracket to make sure... i know the throw out bearing is noisy and going bad but idk if that would have anything to do with the idle

p.s.
its a d15b but wired obd0 with an si harness and a pm6 ecu and its still got the d15b manifold (obd1) so the map sensor on top of the throttle body is till unpluged, and the vtec i not hooked up... do you think this poses a problem with the idle???

 

bump

 

As stupid as it sounds, double check EVERY vacum line on the manifold. Make sure everything is plugged in and nothing is left exposed.

I too once messed with the iacv and idle adjustment, and then I noticed one of the lines popped off and had fallen behind where I couldnt see it dangling. D'OH!

good luck
