N14 Cummins C+ miss & smoke...

**Gambi80** · 08.19.2012

Started pullin this crap the other day ... http://www.youtube.com/watch?v=zDkp6...e_gdata_player ...Does it only when cold, for a couple min at start-up. Seems like its missing 2 cylinders and blowing blue smoke...smells like 'poorly' burnt fuel. Any ideas?

Injectors. Imediately after start up feel the exhaust manifold at each port, the bad ones will take a bit longer to heat up.

Check wiring harness, but probably inhectors. Tried any fuel additive ?

I should try or have I tried additive...?? Only thing I use is stanadyne(sp?) anti-gel in the cold.

When last did you do settings on the injectors?

Try what I explained in my first post, at least then you can pin point the injector giving you the problem. Try a fuel additive like jbatmick suggested. If that doesnt resolve the issue, I would just make sure the settings are in order if all is well I guess you will have to pull the injectors and have it tested.
