Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and blockages.
Install a new air filter, ensuring it fits securely, and reattach the housing cover.
Tools Required: Socket set

3. Fuel System Check

Inspect the fuel lines for any visible leaks.
Check the fuel filter and replace it if it hasn’t been changed according to the maintenance schedule.
Use a fuel pressure gauge to test the fuel pressure; compare it with manufacturer specifications.
Tools Required: Fuel pressure gauge, wrench set

4. Throttle Body Cleaning

Remove the throttle body using a socket set.
Clean the throttle body with throttle body cleaner and a soft cloth, removing any carbon buildup.
Reinstall the throttle body, ensuring all bolts are torqued to specification.
Tools Required: Socket set, throttle body cleaner

5. Ignition System Inspection

Remove the spark plugs using a spark plug socket.
Inspect each spark plug for wear; replace any that appear damaged or fouled.
Check ignition coils for proper operation; replace if necessary.
Tools Required: Spark plug socket, torque wrench

6. MAF Sensor Cleaning

Disconnect the MAF sensor connector and remove it from the intake.
