Just curious if anyone else continues to experience white smoke and rough idle upon a cold start... even after having the TSB 18-037-04 reflash done?
Saw my fuel milage go up on the overhead about 1. 5 or 2 mpg after the reflash, but I still have the smoke and rough idle.
I'm thinking it could be an injector issue. Anyone had to replace a bad injector on a 04. 5?
BTW... truck has 8700 miles on it.
