2. Replace Air Filter

Open the air filter housing.
Remove the old air filter.
Install a new, clean air filter that meets OEM specifications.
Secure the housing cover.

3. Clean or Replace Fuel Injectors

Remove the fuel rail from the engine.
Disconnect the fuel lines using a line wrench.
Remove the fuel injectors from the rail.
Clean the injectors using a fuel injector cleaning kit or replace them if damaged.
Reinstall the cleaned or new injectors and reassemble the fuel rail.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers (if applicable).
Use a spark plug socket to remove each spark plug.
Inspect plugs for wear; replace them if necessary with OEM or equivalent plugs.
Reinstall the spark plugs and reconnect the ignition coils.

5. Tire Pressure Adjustment
