Have you ever changed the PCV? Positive crankcase ventilation. They are only about $5 or so.
Did this problem begin all at once or gradual?

Does it act this way whether in neutral, drive or both. Engine and trans mounts are not out of the question.

My initial thoughts were charging system problem. I used to have a Honda with a bad alternator and it would cause violent shakes in the engine with increased draw like headlights or AC. Went in for battery check, they said it was alternator not battery. Changed it for a new one. Problems resolved.
