When I start my H23 cold, it idles at 3k! As it warms up it drops down to 2k... I cleaned the IACV, didn't help at all. When I unplug the 2P connection at the IACV it drops to 1200 rpm and bounces up and down at idle. I tried the idle adjust screw but idle doesn't move at all with the screw in full left or right positions. I don't seem to have any vacuum leaks either. Can any one help? I have a 93 prelude Si
Thanx...
