7.3 idi hard start

  1. 99-03 7.3L General Discussion
    My 2002 7.3 has great power and runs great until it STOPS! It usually happens when I take my foot of the pedal or stop at a stop light. When the engine retards from being under power to idle it'll shot off suddenly and without warning. It's hard to restart often requiring me to move the water...
