Hi there,

The code, P0300 means there are multiple misfires on the engine. You feel this with the bad shaking. Normally I suggest starting with a complete tune up and a fuel sample. If you have water in the gas it can cause this type of issu, but also a bad distributor cap, rotor and plug wires can do this, as well as bad plugs. So, I would suggest starting with a tune up.
