Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another.
Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
The crankshaft and camshaft sensors monitor engine speed. When the sensors detect a change in speed, they attribute it to a misfire. Depending on the cylinder that was supposed to fire, the engine can determine when the change in speed took place and can single out a particular cylinder. When it happens with more than one cylinder, it becomes a mulit cyl misfire. This is one of the symptoms of a malfunctioning cam or crank sensor.
