I have had my 03 7.3 with manual trans 2wd for 5 yrs and it has always ran great, until the other day, it has 72000 miles on it , I'm hoping to learn what the problem might be ,I think it maybe the uvc harness, but thought I ask and find out if there maybe other reasons for it running like it dose, it starts and runs fine for a 1-2 mins, then its like rpms spike, shakes misses like its lost half the cylinders, it made it home and seamed to run okay at 20 to 50 mph, Ive shut it off and on several times runs ok for a little bit, then look out, any suggestions Thanks in advance
