Then start it in-between when you stop it and stop it. Or is it that it sits out at night?

99% injectors

I had the same problem, 265 k on my 01' f250.... i own a shop in Nor california.... replaced all 8 injectors and o-rings plus vc gaskets and under vc harnesses and the thing runs like its new!!!! i wont say 100% it is injectors but sounds like the same problem i had (cold start or even just after sitting all day at work it felt like 3 cylinders out of 8 were not firing) and it fixed me up!! go to beans diesel and get the stock used ones for 118$ a piece. They are super nice guys and the parts worked great!

pm me if you need more info.

phil
