I have an early 03 6.0 that has beed the biggest pos. I can only get 2 or 3k miles out of it before I have to send it to the shop. Usually it is sensor related. Is there aftermarket componets that will help me keep it on the road longer? Do you know of a shop that can get the problems with this truck ironed out? Should I just fix it and sell it? My 04 and 06 6.0's run great.
