Recently purchased this and ran great for the first week, now when starting it will have lots of white smoke, takes about 30 minutes to stop smoking/warm up, then when driving it seems to have no power. When it does finally get going, the automatic gear changes jerk really bad.
Lots of white smoke upon starting, poor performance after warm up. on 2002 Ford F-350 Super Duty
This is not a good sign, especially if you just purchased the truck. Take it back to where you bought it if possible, this sounds like a blown head gasket.
