Remove the air filter housing cover using a socket set.
Inspect the air filter; if dirty, replace it with a new one.
Reassemble the air filter housing cover.

3. Fuel System Check

Use a fuel pressure gauge to check the fuel pump's output.
If pressure is low, replace the fuel pump as needed.
Ensure fuel lines are not clogged or leaking.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body with throttle body cleaner and a soft brush.
Reinstall the throttle body and reconnect all electrical connectors.

5. Spark Plug Inspection and Replacement

Remove the spark plug wires and use a socket to take out the spark plugs.
Check the spark plugs for wear; replace if necessary with OEM specifications.
Reinstall the spark plugs and wires securely.

6. MAF Sensor Cleaning

Carefully disconnect the MAF sensor from the air intake tube.
Use MAF cleaner to clean the sensor element; avoid touching it with fingers.
Reinstall the MAF sensor and ensure all connections are secure.
