Shaking engine is due to a misfire. Usually that is related to worn spark plugs, and if you continue to run it that way, the unburned fuel going into the catalytic converter will overheat it and destroy it. That turns a simple tune-up into a very expensive repair. At the mileage you listed, it's way past due for a tune-up, so start with that.
