6.0 powerstroke runs rough after starting
I have a 2005 6.0 powerstroke dually that runs rough after starting and pumps white smoke out of tailpipe until engine comes up to temperature. Ususally take 10 minutes. Does anybody have any ideas as to how to fix this. It is worse in cold weather, but does it any time the engine temperature drops after sitting overnight. If I plug in the block heater, the rough idle and white smoke go away more quickly. We live in Angleton, Texas so it's not real cold on the gulf coast. I'm not familiar with the term "reflash" which I have seen on other posts.
