n14 misfire under load and at hot idle

So did you get the problem fixed? my 2003 N14 is doing the samething. When you mash on it an shift it misses and shakes.

 

Wondering if any of you got it fixed? Thanks!

 

Thanks for prompt response!
In my case there is no miss when engine is cold, after running not even a minute, it starts missing, miss was on #4, put 2 new injectors on #3 and #4 and miss moved to #3. Just when installing #3 it didnt feel so tide as on #4. I wonder could injector cap be bad on #3.
Other than leaking diesel in to antifreeze (dont have this problem), what are other signs of bad injector cups?
Can bad injector cup cause low fuel pressure or injector misfire in Cummins N14 Celect Plus?

 

I have heard this misfire issue can be caused by a hot ecm. Fuel goes through the back of ecm. But I may be thinking of isx ecm. I am thinking out loud.

 

Hello am having a similar problem
My n14+ starts to miss intermittently after about 30min- 1hr of driving and sooner if am pulling something. This miss is on the 4th cylinder. When the truck starts up after overnight every thing is working great all cylinders make a difference in sound when plugged out. Only after running the motor for so long number 4 doesn’t makes a difference.

New ECM did the trick for me

 

Ok thankyou for sharing that’s probably the next thing to do

 

Swap injectors with #3 and see if the problem follows the injector or stays in #4. Likely just a failing injector.
