Could use some direction to start. Usually when AC is on (but not always) when engine is NOT up to operating temp. Put in gear step on brake and I get a idle from 600-1200/1300 once or twice then dies(only happened 1 or 2 times w/o AC) I've checked for vacuum leaks and found 2(fixed)also checked the IAC- clean (no carbon) I will crack out the meter and check for volts and ohms this weekend but any other areas to look at? W AC on idle is about 550(too low?)Also when AC is turned on/off the only idle change is down(700-550) Am I even looking in the right direction? Any help much appreceated! Also can give more info to help!!!!!
