E7 400 Mack, Misfire, seems to Move, need help
in Engine and Transmission

Hello I’m also having a similar issue. Engine sputters while running. Codes were EUP 2, 3 and 6. Turns out 6 was the bad one. I also switched out all fuel lines. It’s been about 3 weeks and it’s sputtering again. Now saying #2 again. Could it be an injector? Should I just swap out the pump? There’s obviously a price difference….appreciate the help
