I have a problem with idling. It won't unless you give it some throttle. There are no pending codes, no MIL light. I have cleaned the throttle body. I have replaced the IAC twice. Both times it solves the problem for a short time (30 minutes to 10 hours) then it goes right back to the same no idle condition. I pulled the master cylinder vac line to keep it running at idle and I have power on all 4 of the IAC wires (pulsing). I boosted the battery and cranked the motor while watching my attached volt meter. Never went below 12 volts. What is left to check?
