My friend's car vibrates terribly. He has changed the gas filter, spark plugs, oil, and spark plug wiring. The car still shakes and the first spark plug is still not working (he pulls it out and the engine still runs "like normal" but if he pulls another one out it does not). Do you have any suggestions on what to look for. It would really be appreciated.
