Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative battery terminal to prevent electrical shock.
• Ensure the engine is cool before starting the repair.

2. Inspect and Replace Spark Plug

• Remove the ignition coil for cylinder 2:
  • Use a socket set to remove the bolts securing the ignition coil.
• Remove the spark plug:
  • Use a spark plug socket to carefully unscrew and remove the spark plug.
• Inspect the spark plug for wear or fouling; replace if necessary using a new spark plug with the correct specifications (typically NGK or Denso for Honda).
• Reinstall the spark plug and torque it to the manufacturer's specification (usually around 13 lb-ft).

3. Inspect and Replace Ignition Coil

• If the ignition coil is suspected to be faulty:
  • Test the coil's resistance with a multimeter (should be in the range specified in the service manual).
  • If faulty, replace with a new ignition coil designed for your vehicle model.
• Reinstall the ignition coil and torque to specifications.

4. Check and Clean Fuel Injector

• If the fuel injector is suspected to be faulty:
  • Remove the injector from cylinder 2.
  • Inspect and clean the injector or replace it with a new one if necessary.
• Reinstall the injector ensuring proper sealing.

5. Reconnect Components and Test

• Reconnect the battery terminal.
• Clear any diagnostic trouble codes with the OBD-II scanner.
• Start the engine and monitor for smooth operation.
