Hi I'm Wayne
I will help you with this
what you are describing is a injector has failed
it is leaking, if you have a infrared heat gun
shine it on each exhaust manifold , and see the temp difference
but I see you say it is not the injectors
then it is a intake valve
that will be the faulty cylinder
I hope this helped you

what application is this used in? most of the DD4 pumps had a cold weather start advance (CSA) that would stick and cause an intermintint issue similar to this. can we have a serial # on the engine?
