This can be caused by the washers that hold the engine are loose or worn down, causing extra vibration when the car is running. Not too expensive to fix but involves taking the engine out and replacing the springs on the washers.

Cylinder miss, broken motor mount, or vacuum leak.
Could be many things. Amoung them, low engine idle, one or more vaccum leaks, engine missing.
Adding heat causes gas molecules to vibrate, increasing the gas volume or pressure. A car with a damaged valve will usually vibrate noisily while operating. Tuning forks are designed to vibrate and thereby create a particular pitch.
Cars vibrate.
If the tires are properly balanced plug tires should not cause a vibration.
If your car is shaking it could be poor suspension alignment can cause a car to shake and vibrate, and other possible causes are bent or worn suspension parts, old tires, bent wheels and bad brakes. If your car sounds especially rough at speed, the problem could lie with the car's spark plugs and wires. Spark plugs fire more frequently the faster you drive, and the engine will sound rough when they begin to fail.
