For Misfire Codes:
- Replace faulty spark plugs and/or ignition coils as indicated by the fault codes.
- Tools Required: Socket set, torque wrench.
- Sub-steps: Remove ignition coils, replace spark plugs with manufacturer-approved parts, and reassemble.
For Emission Codes:
- Inspect and replace the catalytic converter if blocked or damaged.
For Fuel System Issues:
- Clean or replace the fuel injectors if they are clogged.
- Check the fuel filter and replace if necessary.

4. Reconnect Battery and Clear Codes
