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. Look for air/vacuum leaks around the intake manifold. Look to see if the EGR valve either leaks or does not seal/fully close. Important to look and see the ignition system isn't causing the misfire/stumble.
