The metal disk part of one of the valves (intake or exhaust, usually the exhaust as it is under the most stress in operation) in one of the engine's cylinders has cracked. This allows gasses from the cylinder to escape, causing that cylinder to be "weaker" than the other ones, increasing engine vibration. If the crack is in an exhaust valve (as it usually is), unburned hydrocarbons in the escaping gas will cause the car to fail emissions testing. If the crack is in an intake valve, very hot escaping gas can cause a type of "backfire" in the engine's air intake system.
