For the past few weeks my truck has been running like a dog in the mornings. If I don't let it warm up for 10 minutes or more it barely wants to climb a 1% grade that's about 100 feet long. It won't shift and feels like there's no power. If I let the truck warm up for 15-20 minutes, it runs fine. Same thing at the end of the work day after the truck's sat all day. Suggestions?
