Food for thought ... .
I went into service for a hard start situation and they told me I had 29% idle time on the motor, they actually showed me the computer pluged in and the readout of 29% they said anything over 19% I belive, IE dont' quote me on the 19% and it was a customer not cummins issue. So I had 2 options do nothing and lower my % or pay for a injector cleaning... . I said see you latter and I don't idle as much. I do have a EX brake now and I use high idle, truck runs great now.
