Are you feeling misfire? What has the maintenance been like? It could be as simple as a faulty spark plug or wire, could be a fuel injector, or even an internal engine concern. The first step would be to isolate it to a specific cylinder, and proceed with diagnosis from there. If it has been a while since tune parts have been replaced, that may be a good idea for a start.
