Typically an overly rich fuel mix will cause a dark smoke with a strong smell of gas. If the smoke is light colored and sweet smelling then it could be a sign of a coolant leak. A blueish colored smoke indicates oil being burnt from a leaking seal or rings.

Usually a rich condition gives a gray/black fuel smoke that smells of gas. Pull your plugs and see how it's running. If it's rich they will be black and greasy.

Typically white smoke would indicate coolant or water being burnt. Black, foul smelling smoke indicates a rich condition and blue usually means it burning oil.

you most likely have an internal collant leak. Black smoke is caused by a rich fuel condition. Blue smoke is caused by oil consumption. when your engine overheats the head gasket can shrink allowing coolant to escape into the combustion chamber. Usually the symptoms are more pronounced when the engine is at normal operating temperature.

It could cause this problem but most likely this is a break in one of the gaskets of the engine. I would try changing them if they are easy to get to.
