I have an 89 chevy corsica with a very high idle it has a throttle body fuel injection system. I have already checked the TPS and it shows proper operating voltage, (.45 to 1.25 at idle). I'm thiking the IAC may be bad it was showing 53 oahms on a to b and c to d terminials any ideas what to check next?
