OK...was out of town for a few days...

The mechanic was able to get rid of the 3 "unknown" codes, but couldn't shake the "random misfire" code. The light kept flashing but he told me to head off on my trip and that maybe we would swap out the plugs like you guys have recommended. He had checked each plug and all seem fine.

Truck drove just fine as well on 600+ mile trip... <img src="/forums/images/graemlins/kewl.gif" alt="" />
