I think we all have similar stories to tell about the first day out in our trucks. For myself, my first trip out the new coil was defective and left me in the middle of a busy intersection. Fixed that, then like pplummer, my new radiator hose from JC also had a pin hole, then etc.. but now I'm working on a shortlist of bugs I've found as I drive it. Now have 1300 miles, moxt of which have been uneventful.
