My 7.3 Tremor King Ranch is in the shop with some gremlins. Last week it didn't want to start and various messages came up on the control panel. After a bit it started and acted fine. Today I was going to grab some lunch and had trouble starting it. It finally turned over on the 3rd or 4th try. As I was driving it the yellow wrench symbol came on and it was running rough. As I continued to drive the service engine light came on. I turned around and parked it so I could call the dealer. When I started it back up to take to the dealer for service it was running great with no warning symbols. Hopefully they can figure it out as I really love the truck. Almost to 1300 miles and it doesn't make you warm and fuzzy feeling about your truck when it has issues this soon. I picked the 7.3 as it is an old school V8 and should be reliable and long lasting. Will post what happens if it is worthy of note.
