I am thinking about buying another truck (WTF)!!! I was the previous owner and know the whole life of the it. It is a 2001 7.3 with 153,000 Mi i put a leveling kit on it, Edge evolution, Cold air intake, 4-5" exhaust, air bags, and now he is telling me #3 and #8 injectors are dead. it is a F-350...
