Welcome to NICO!I'm sorry Im not much help the only thing I can think of is fuel, I've had fuel pumps fail that casued similar bucking, and it was an intermitant failure, it started happening at lower rpm as the pump grew weaker, you might want to have the codes read as well, I knwo the knock sensor ann cause some drama
