What is the simple method to identify a misfiring cylinder?

The simple method to identify a misfiring cylinder is: unplug the fuel injector of each cylinder and observe the vibration amplitude. For a four-cylinder engine, start with the first cylinder and unplug the fuel injectors one by one. If the vibration increases when unplugged and disappears when plugged back in, it indicates that the cylinder is normal; if there is no reaction when unplugged, it means there is an issue with the cylinder, and a new spark plug needs to be replaced. If the engine still has problems after replacing the spark plug, you can check the ignition coils of each cylinder. Swap the ignition coil of one cylinder with another and observe if there is an issue with the ignition coil. If there is, simply replace the ignition coil.
