Ok so first I need to know your engine layout. Are all those cylinders on one side or are they alternating. If you have a diagnostic tester check for codes. If not let me know and I will see what I can do. I think it is most likely a misfire in those cylinders. There are a lot of things that could cause this but the most likely is a clogged catalytic converter. I would check the Cat first and if that does not help let me know.
