I did replace a couple injectors here and there then a whole new set last fall at about 475,000 miles. The injector wiring harnesses have all been replaced at some point. That seems to be the week link to me. Still drive it almost every day. Have a 2015 Duramax I bought last year and it sets most of the time.
    Very cool!

    Thats awesome, those LB7 are great motors. How often do you change your oil? Run any fuel additive? Gone through any injectors?
