| I would talk to your dealer and see what they say. Most people are getting the injectors covered under the special policy for the 01-03. (even the 04s since they are the same injectors) 7yr/200,000 miles. It sounds like another set of injectors to me. How is your coolant level. Does your truck pressurize the overflow tank after running for a short time? How about after sitting overnight?
