    Yesterday I started to have this problem with my 06 vnl670 and 465 vd12, injector 4,5 and once 6 started to go off with electrical fault. but when I turn off the engine and start it all injectors will work OK for some time. So I was dialing with this problem just to come back home and was shutting the engine when ever the injector go off and after that it was ok. CAN ENYONE TELL ME IF IT IS INJECTOR REPLACIN THE BEST TO DO OR IT IS SOME ELECTRICAL OR SOMMETHING ELSE because the engine and injectors are running great after I turn off and restart the engine??????????????

    One injector can also cause the other two to go bad since they share electrical open your valve cover and check the injector spring if one of them is broke it will cause extra mechanical resistance which in turn will increase the current draw to that injector and cause problems. In my experience I have seen this a lot of times.

    I had similiar problem with only one injector.. from time to time it would throw check engine code with injector electrical fault and cause misfire on the engine.. after restarting the truck problem would go away for a 20-100 miles..

    I replaced the injector and no problem ever since.. but it would only give one code for only one injector not 3 of them at once

    good luck
