3. Check and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coils from the spark plug wells by unscrewing them.
2. Use a spark plug socket to remove the old spark plugs.
3. Install new spark plugs, ensuring to gap them according to specifications (usually around 0.043 inches).
4. Reinstall the ignition coils and secure them properly.

4. Inspect and Clean Fuel Injectors

Sub-steps:
1. Remove the fuel rail assembly, disconnecting fuel lines and electrical connectors.
2. Remove the fuel injectors from the fuel rail.
