I have just traded from a 2001 Chev. ext cab, 3/4 ton, long bed, 2 wheel drive duramax, 56000 miles, to a 2005 GMC Crew Cab, one ton, Long bed, 4 wheel drive 34000 miles. One reason I traded is because of the potential and everlasting injector problem with the 2001. They were replaced at 51,000. I haven't seen any post regarding injector problems with the 05. Did I just miss them? What can I expect from the 05?
