How to Diagnose a Faulty Ignition Coil

Diagnosing an ignition coin fault on a 2001 Nissan Micra K11 1.0L using an OBD2 U480 diagnostic scanner tool. The engine was running rough so I suspected either a spark plug or ignition coil was at fault. I ran a scan and it showed error P0302 which was a misfire on cylinder 2. To confirm the issue was with the coil pack and not some other problem on cylinder 2, I swapped the coil packs on cylinders 2 and 4 and retested it using the scanner. This time the misfire was showing on cylinder 4 which confirmed that the problem was the coil pack. Turn off the car ignition fully each time before touching the coils to prevent electric shock.
