Low Idling Speed when cold
Hey Folks,
Got a 95 Ranger. It just got cold here and the high idle when starting doesn't seem to work. Once the truck warms up, it runs great. I also noticed that the automatic AC compressor engagement doesn't seem to be working. Only recent repairs was a new heater core and radiator repair. Any ideas???>
Thx,
David

IAC would be my first guess. Possibly a vacuum leak or a slightly stuck open EGR too.
If the AC clutch isn't kicking in defrost mode I'd first look to see if the wire is getting a signal. If not check the fuses. If so put a 12v power to it to see if it'll physically work. If it does.. low refergerant most likely.
