Answer
I would recommend that you take the car someplace to have a computer diagnostic done. Most national auto parts stores will scan you vehicle for free. But they won't be able to do any in-depth diagnostics, for that you'll need to go to a reputable repair facility. I would suspect either a failing coolant temperature sensor, a slow oxygen sensor, sticky EGR valve or a gummed-up throttle body butterfly valve. All would give the symptoms you've described.
