I have a 4.0 that idles high, 1100-1200ish rpm, then will drop and rough idle 800-900rpm where it will almost die. I have replaced all vac lines with new, new plugs and wires, new Idle control valve, no dash lights. Where should I look next? Truck has plenty of power, no real hesitation, just rough and random idle when at a stop light or left sitting while idling. One thing I have noticed is my temp gauge doesn't seem to get very warm and I am suspecting a stuck thermostat. Would this cause a random idle issue?
