It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. The code is for a general misfire, it unfortunately does not identify the cylinder/s that are misfiring. Check the engine basics first, (good even compression), check that the ignition system is in good order, look for vacuum leak at the intake manifold, confirm fuel pressure and volume delivery, and the the fuel injectors spray correctly good clean pattern.
