Thank Jeff. Shaking or vibration may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal.
What should I do after replacing coils and spark plugs?
The code P0353 on this after you only had misfire codes and you changed the coil and plugs on cylinder number 3. You should disconnect cylinder coil and check connector and pins in coil are not damaged and if they are okay then try to install another coil to see if you got a bad new coil.

Why is my CYL # 3 spark plug not working?
A damaged seal can also explain the rough idle and shaking, not only because unmetered air can get in, but metered fuel can wind up not reaching the cylinders as well, resulting in a lean condition that explains the physical appearance of the Cyl #3 spark plug.
