Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt and debris.
Replace with a new air filter that meets OEM specifications.
Reinstall the housing cover and secure it properly.

3. Check and Inflate Tires

Use a tire pressure gauge to measure the tire pressure.
Inflate tires to the recommended PSI as listed on the driver’s door jamb.
Rotate tires if uneven wear is observed.

4. Replace Spark Plugs

Remove the ignition coil cover by unscrewing it.
Disconnect each ignition coil and unscrew the spark plugs using a socket wrench.
Install new spark plugs, ensuring to use the correct gap as specified in the owner’s manual.
Reconnect the ignition coils and replace the cover.

5. Assess and Repair Fuel System

Inspect fuel lines for leaks; replace any damaged sections.
Check the fuel filter; replace if clogged or according to the maintenance schedule.
If low fuel pressure is detected, consider replacing the fuel pump.

6. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and monitor for any reoccurring codes or issues.
