I Bought a new 2003 F250 power stroke 6.0 diesel lariet extended cab short bed with 4 wheel drive in April of 2003. Bad mistake! At 250 miles engine developed serious missfire which turned out to be broken rocker arms on two cylinders. Two weeks at dealer before it was fixed. At 15,000 miles the engine developed a fuel leak. At 20,000 miles (this past December 2006) while at a Ford dealer for oil change etc dealer informed me that the truck would'nt start! After 6 weeks the dealer finally returned the truck to me as fixed. It was not! Now it has no power and a overheating problem when pulling a horse trailer. By the way don't count on ford regional or national customer service to help you. Ford Sucks.
