Cummins Surging??
I have noticed since i got the truck that when i start er up, the engine will surge every 5 to 7 seconds like a couple valves are working harder than the rest. than it seem to go away after a while. truck not warm yet? anyone else had this happen? i am losing power, im just wondering what it is. Thanks

mine does that as well, from what ive heard, its caused by two things, big sticks and a cold motor. youve got 150 stick like i do, let her warm up for a few minutes, then it should go away. its called valve knock, ive talked to cummins, they ask if i had checked my valve lash, so i did, adjusted it a little bit, and that seemed to help some.
