This truck develops a miss, mild to severe after it is warmed up; driven 25 to 30 miles.Really noticable at 55 to 60 mph.

Has the injector pump quit yet?

The 5.9 is a diesel, no plugs in it.

A diesel won’t miss long before it lets you know why. Basically, you need 3 things to run, compression, fuel, and air. The chances are it’s not an air problem if it’s only 1 cylinder, so that leaves compression and fuel.

Fuel could be several things. Your injector pump could be down on one cylinder. You could have a bad injector. You could also have another problem in that cylinder that affects compression. It could be a busted piston, broke valve, cracked head, broken glow plug that’s causing a compression leak. (some Cummins do not have glow plugs, some have manifold heaters.)

That’s hard to diagnose with not much information on it.

The Cummins is a 5.9 as well, suppose it could be either.
