Is the service engine light on? If it is, I know Autozone can check the code and see what's causing the problem. It could be the oxygen sensor or fuel pressure regulator. As far as the smoking on start up, its probably the valve guide seals gone bad, letting oil drip into the cylinders when the engine sits for awhile.
