Everyone's comments above are absolutely correct, I was going to mention that earlier, if your car is this old and has never had Engine mounts replaced it is time. My car shook like shaggy from Scooby Doo, even the bubblewrap trick I explained earlier only helped part of the problem and covered up a Symptom of a much larger problem which was the motor mounts. Visual inspection was not enough, a couple were shot but a couple looked fine, so I only replaced two and it helped with the vibration but not entirely. Only until I replaced the other two did the vibrations stop.
I was truly shocked after all four were replaced, the car has zero rattles and is much more a pleasure to drive. Also you will notice a bit more power because there is less slop between the engine and the rest of the car and therefore power delivery is instant. I liken it to trying to run when your shoelaces are loose versus having them tight, it makes a huge difference in the car.
