anyone ever heard of injectors going bad on a Cummins?
As for the bosch injector in the cummins they are blaiming it on the fuel quality. I'm not 100% convinced but I'm sure it does not help.
I do a lot of cr injectors. Seem to do more 04.5+ 5 hole injectors with the three injection firing event that the 03-04 7 hole two injection event.
