I installed 370 marine injectors in my cummins. When its cold it will sound like a slight miss then it goes away and it will do it a couple times while it idles... also when its cold and i take off it will lug alittle like the engine breaks up some then clears out and is fine... now Idk if its cause i have the 181 Dv in still the guy said they would fuel the 370s but input from everyone would be great... I have new fuel filter I did run my tank alittle low once and. Did it but cleared up now two weeks later its doing it again so Idk I put fuel treatment in it Incase I had water in the tank or something ....any ideas?

 

181's are good to 800HP thats not your problem.

 

Think its cause I mite of sucked something up? It didnt do it until that day I ran it low and it sucked alittle air.... and didnt do it all day today went all the way to NYC and back
