If your vehicle is turbo equipped, you might notice a hesitation on acceleration under certain conditions. As far as the sputtering is concerned, that is an engine controls issue that would have to be looked into. The air fuel ratio is off, under certain operating conditions, and/or there is a fault in the ignition system. The issue could be in the air induction system, mass air flow sensor, EGR system and quite a few other "systems". You could have a vacuum leak. Check for diagnostic troubles codes stored in the engine computer and look, too, at secondary firing patterns at idle to see if those traces hold any clues.
