If your car shakes while underway, your tires have worn incorrectly from misalignment. If it shakes while in park or not moving, your engine is misfiring.
Its either timing or fuel intake problem.
if it shakes while your braking your front roters could be warped or if it shakes while your driving try balancing the tires at a tire shop.
you will need a front wheel alignment
You may have a ball joint going out or your wheels are unbalanced
maybe you should try to install some strut bars on top of your engine to hold it in place.
