I think he had mentioned that he had replaced/cleaned the EGR, so that cant be the issue. Even after cleaning my EGR, I still notice bucking sometimes. I did try an experiment once, where I disconnected the EVAP purge valve and block off the hose going to it, and the bucking seemed to have reduced. Maybe try that and see if the problem is not in the EVAP system.
