On my way home from work this morning my truck sounded a little off. It seemed like I could hear the engine noise in the cab more. The truck was pouring out white smoke when accelerating which is normal in the cold. When I got home I put it in park and slowly brought up the RPM's. At around 2500-2800 I could feel a skip or miss. Also had light blue smoke. I checked the oil level and smelled for fuel and both were fine. When I drove back to work this afternoon the truck ran normal again. This morning was about 0 deg. out this afternoon was around 32. Anybody have this happen?
