OK, I have been noticing that when the temp drops into the lower 50s and 40s, my truck (which is garaged) starts but runs ROUGH and throws a little white smoke out for about 30 seconds.

I DID the TSB re-flash.
It only has 3K
It runs fine otherwise
My oil level did NOT increase

Is this NORMAL or could it be a sign of an injector leaking and going bad???

 

Anyone out there???

i had an 03 do the same thing and nothing wrong with it, just dont run as efficient when they are cold

 

My truck hasnt done it but we got 2 6.0s on 03 one 05 and both of them white smoke horibly in the mornins if it is cool out.

 

I remember my truck doing that (white smoke on start up) winter before last. It finally just went away on it's own with no problems.

Clogged injector maybe? Maybe try running some biodiesel in it to clean it out. Also, after the truck is warmed up...go run it hard and get your EGTs pretty high to help blow it out.
