ANSWER by , September 30, 2010
I'm not entirely certain, as I would have to see the smoke...but whitish/bluish smoke that goes away after initial acceleration sounds like internal oil consumption - oil getting past the rings and burning. Not at all uncommon with that 4.6L V8, especially if the oil has not been changed at 3,000 - 5,000 mile intervals for the life of the car. If this is the cause: fixing it is pretty much more costly than it's worth - engine overhaul; replacement of the engine. I would continue to drive it and monitor oil level.

If it's truly white smoke, that's steam. Water getting into your combustion chamber is usually a bad head gasket
