Hello IA i have a 98 civic hatch with a 98 gsr in it ecu,tranny, the works. The problem im having is my car will idle fine and everything warm or cold but once i get the car going it will have a sticking idle around 2000-2500 rpms. It does this driving normally once i put it in neutral the idle does not come down it stays around that area. But once i come to a dead stop it will idle perfectly fine again. It use to actually idle around 2500-3000 rpms but i got a iacv from a friend and now it idles perfectly fine except from what Ive explained. Please help me out its confusing the hell out of me thanks.
