Kind of a popping sound out the stacks
No power in top gear
White gray smoke in top gear
Couldn't barely pull an overpass with an empty wagon..Brettj3876 and AModelCat Thank this. -
Sounds like it might be an injector dumping fuel.

Do a cyl cutout test?

The thing is that popping sound kind of comes on the passenger side like it’s hitting my cab
