I worked on an '04 earlier this week. It had some cold misfire issues and intermittent stumble with heavy smoke problems. A simple injector module reprogram cured the misfire. The stumble was caused by a faulty egr valve. Two really easy fixes to turn some major driveablilty issues into a smooth running truck.
