I checked the raidiator fluid and was good, pulled of the oil cap and no milky build up, it had the #3 engine misfire so switched the #1 coil pac with the number #3 coil pac and the miss moved with it, with truck running I can pull the#4 plug wire and the miss stays the same so I'm hoping its just a coil going bad when heating up, like I said it runs perfect until operating range, and it has never ran hot
