White smoke (more like steam and has a sweet smell?) bluish white smoke (acrid oder, smells like burning oil?) or Black smoke (smells like gasoline?)...and its coming right out of the tailpipe? or is it possibly burning off the engine somwhere? (maybe you spilled some oil when you were changing it?)

Also recheck your fluids, make sure your oil is amber and your coolant is green (or orange if you use that kind). If your fluids are ok, let it idle and reach normal operating temp. Watch it closely, look for the source of an leaking fluids. Watch the temperature gauge, and pay attention to any funny noises or anything out of the ordinary.

Let us know what you find out.
