The number three cylinder isn't working. I already checked the spark plugs and wires and they work. The other cylinders are working. My engine is shaking pretty bad. I think I might have a dead whole. Or I need a new valve. Any ideas?

How did you check the plug wires? Eye balling it is not reliable-use an ohmmeter to check its resistances.

Have you check for a cyclinder leakage on the no.3

Sure its not an engine mount

I checked the wires and the resistance is fine. Since my third isnt working, would that make my engine shake bad. Should it be running fine. How would I check for leakage?

You need to check the compression on it wet and dry test.

Not satisfied-if you got a compressor pressurize the cylinder with correct adapter and see where its leaking on the no.3 cylinder

Pointers: 1. Coming out of the dipstick points to rings
2. Out of the throttle body- intake valve
3. Out of the exhaust -exhaust valve

HTH Good Luck
