Had a misfire in my Celect Plus so I put all 6 new injectors in. Before this I also had an issue where if the truck would sit for more than 3 days or so, it would crank unevenly and when it would start it would dump a ton of black/gray smoke out the pipes. After the new injectors it runs perfectly smooth again, but it started doing the uneven crank and dumping smoke on startup after it sits for a few days again. Did I just luck out and get another leaking injector out of the box or is there something else that can cause this? It's definitely raw diesel smoke not antifreeze as well. Never did check which cylinder was doing it before the 6 pack, so I won't know whether it's the same one or not.
N14 Injectors Leaking Down?

I was told after I did a six pack, just replace the problem injector due to the poor quality of most Cummins reman parts.
They say clean your ground's, while you will find some corrsion somewhere, I think unhooking battery's and doing a ECM reboot is often what helps?
I've had the out of the blue popping chugging, smoking thing also??
Next time starts normal.
One thing that seems to proceed wierd starts is rushing a start, I count 15 seconds to allow ecm click thru and it seems to help.
They are frustrating little red head girls
