Tools Required: Fuel injector cleaning kit (or replacement injectors), safety glasses
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel injectors' electrical connectors and fuel lines.
Remove the fuel injectors from the intake manifold.
Clean injectors using a cleaning kit or replace them with new ones.
Reassemble the fuel system and reconnect the battery.

4. Replace Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, torque wrench, socket set
Remove the ignition coil covers (if applicable).
Disconnect the ignition coils from the spark plugs.
Remove old spark plugs using a spark plug socket.
Install new spark plugs and torque them to the specified value.
Reconnect the ignition coils and covers.

5. Inspect and Replace Air Filter

Tools Required: None (if easy access)
