I am new to the site but not new top mechanics am fairly new to diesel and justpopped my Cummins cherry with this truck

My problem is I turned up my pump got it running good then I bought some used marine injectors and now the truck has a miss at 1000 to 1100 rpms then clears up and its mainly under load any help would be great cause I'm bout to get some delivery valves 3k gsk and timing bump will this help or make it worse

Do you think I should put my factory ones back in and get the marine injectors checked to see if one is weak or do you think they are just putting to much fuel in for factory timing

 

Dude people come here to get good advice and a&& holes like you f it up for every one I'm leaving in three months to go over seas and possible die for your dumb a&& besides was trying to make a joke
so if you don't have any constructive advice get lost

 

what size injectors

 

I believe they are the 370's but not positive

 

i have put in brand new injectors in my 96 and 06 both had a slight stumble when i would hammer it from a slow roll.i got a bigger charger on the 06 and it runs fine now.you may just need more air.i would first try changing the fuel filter and fill the filter housing full of injector cleaner

 

Its not when I hammer its when I am rolling along and it locks the converter at rpms around 1000 or if I power brake it at that rpm to act like I'm towing

 

Set up my appointment to get the work done so I will find it if more timing will fix my chug I think the new injectors aren't getting enough time for the fuel to burn properly and if it still chugs afterwords I still have my factory injectors
