this is not for me its one of my friends trucks. when he starts it up in the am, it smokes really bad white smoke and it is thick not just a haze. the truck is also idling rough. After a min or so the smoke stops and the trucks idle smooths out to normal. Any ideas on what this could be? Thanks for any input. Oh the truck is an 07 6 speed 4x4 all stock. no chip or anything. the truck only has 4000 miles on it.

Thanks,
Michael

 

Stuck injector... take back to shop immediately under warranty.

 

Really? A stuck injector will cause white smoke to come out on start up? And then disappear as it warms up?

How does that work?

 

Ill definitely tell him. I surely didnt have an idea.
