Remove the engine cover if applicable.
Use a spark plug socket to unscrew and remove the old spark plugs.
Inspect the old spark plugs for signs of wear or carbon buildup.
Install new spark plugs, ensuring they are gapped correctly to manufacturer specifications.
Torque the spark plugs to the recommended value (usually around 15-20 Nm).

3. Check and Replace Ignition Coils (if necessary)

Disconnect the electrical connectors from the ignition coils.
Unscrew the ignition coils from the engine.
Install new ignition coils, ensuring they are seated properly.
Reconnect the electrical connectors.

4. Inspect and Clean Fuel Injectors

Remove the fuel rail as necessary to access the fuel injectors.
Use a fuel injector cleaning kit or professional cleaning service to clean the injectors.
Reinstall the fuel injectors and fuel rail, ensuring proper sealing.

5. Conduct Compression Test

Remove spark plugs and insert the compression tester into the spark plug holes.
Crank the engine and record the compression readings for each cylinder.
Compare the readings with manufacturer specifications; if low, further investigation is needed.
