idle problems 4.7l quad cab 2000 model
Hi
I was wondering if someone could tell what might be wrong , when my truck is idleing with the heater/cooling fan on it goes way up and idles at about 1000-1400 rpm same if I turn on the ac as soon as I turn it off it drops down to 600-800 rpm . what could be causing this ? has any one had this problem?
