Do a tune up. New spark plugs work wonders. EGR exhaust gas return valve maybe stuck open, or the cold start injector may be stuck open (flooding the engine). Inspect your plugs if they look ok, they probably are unless they are over about 35K miles, check the wires too, pull one off at a time and ground it out to something metal on the engine, if you see it ark it's ok move on to the next if not replace it. Heat and stress can break down the wires.
