    Pablo today before I changed injectors I did injector balancing test again and injector #2 was -40% but this time injector #4 was showing +40%, 5th one was "normal" (+10%)

    so I changed 2 and 4 and programmed all 6 trim codes because all of them wasnt maching previous trim codes in EECM..

    after all that I did balancing test again and again injector #2 is -40% but all others seem to be OK..

    Why its the same with new injectors in? Engine seems to misfire and has no power

    Compression test shows 95% on all cylinders and there are no error codes

    I did so much on this truck dont know where else to go :(

    Please help

    Reset injector ballancing values now, after you change injectors

    I did reset injector balancing values and it is still the same: injector #2 is -45% and inject #5 is +50% and over .. what else can be wrong? engine harness?

    the problem is in injector #5. Change it too.

    Really we use to change all injectors on D12 engines. They are old now.... no reason to do one by one....
