I have a 1999, F250 with a 7.3L that may be gets driven amount 5K a year. I usually only use it for heavy hauling, i it sirs in my pole barn post of the time. It only has about 102K miles on it.


Today I started it and the check engine lite soon (saying engine maintenance needed soon. But that was the only message I got. The truck runs great, and completely stock. There are no problems with shifting, an it is NOT a dog. Any Ides where I can start my search would be greatly appreciated,
