Already have done all of this. 350000 on injectors
Expert:  Wayne replied 2 years ago.


Thank you for that

Ok, so we know harness is good

350K is time for injectors, and over head run

I suggest to get this done

Customer: replied 2 years ago.
350,000 is not a lot of miles on injectors. If one goes bad they don't keep working and not working. That is what I have been told by 3 different shops. Overhead has been done

You are correct, to a point

350K is not a lot of miles but Cummins recommend replace at 350K
