Basically what the title says. Just bought an 88 2.3 and when warm will idle super high, from the sound like 2200 rpm. Unplug iac, engine stalls. If I remove the IAC hose, I can throttle the air with my thumb and get it to idle perfect. So I think the computer is commanding the high idle for some reason. Can't figure out why. Cleaned the IAC didn't help. Anyone have ideas?
