Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.

2. Remove Spark Plug and Ignition Coil

Remove the engine cover if applicable.
Disconnect the electrical connector from the ignition coil at cylinder 2.
Unbolt and remove the ignition coil from cylinder 2.
Use a spark plug socket to unscrew and remove the spark plug from cylinder 2.

3. Inspect and Replace Components

Inspect the spark plug for fouling or wear; replace if necessary.
Inspect the ignition coil for signs of damage or carbon tracking; replace if faulty.
If applicable, test the resistance of the ignition coil using a multimeter (should typically be within manufacturer specifications).

4. Check Fuel Injector

Disconnect the fuel injector connector for cylinder 2.
Use a noid light to check for proper signal to the injector when cranking the engine; replace injector if no signal is detected.
If the injector is operational, clean it using a suitable fuel injector cleaner.

5. Reassemble and Test

Reinstall the spark plug and ignition coil.
Reconnect the electrical connectors and ensure all components are secure.
Reconnect the negative terminal of the battery.
Start the engine and monitor for any misfire symptoms.
