They are "foweled". To much fuel. Replace all 4 plugs. The one's that are foweled will never be right again.

Could be leaking injectors, blown head gasket. Disable the spark and crank the engine over and see if it is coolant or fuel that is blown out of the 2 that are wet, that will tell you if it is injectors or gasket.
