Ok, I got a 1990 CRX Si, with a S1 B16a1 in it, and I am getting a really high idle when the IAC is plugged in and a up and down idle like 1g to 2g idle when its not plugged in.. I put a straight 12v connection and ground to the IAC to see if the sensor is messed but it clicks fine, and then I tested to see if there was voltage comming from the harness and it has battery voltage.. So I have no idea what the problem could be.. if anyone has any ideas it would really help me out...

Thanx.. Pete
