Got in the truck to take the wife around town...Playing taxi driver, but not getting paid The truck worked fine yesterday, but when we started out the check engine light came on. I noticed an immediate loss of power, the truck was vibrating and felt like a few cylinders were not firing. I immediately called the dealer and told them what was going on. They told me as long as the check engine light was steady I was ok to drive it to the dealer. I dropped it off Saturday afternoon, they said they would try and get to it on Monday. I will let everyone know what they find.
