Slight Run On

Hello everyone, My 1997 C230 has some slight run on when turning off the ignition. Thinking about one crank revolution. The car shakes for that moment. Feels like bad motor mounts but they have been replaced two weeks ago (did this problem before the mounts too). Plugs and wires been replaced last month. It almost feels as if carbon build up is on the plugs but they are new. I have had some good experience with seafoam on other cars but a MB I'm not sure. Any Ideas?
