Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Socket set
- Fuel pressure gauge
- Screwdriver set
- Cleaning supplies (throttle body cleaner, cloth)
Disconnect the negative battery terminal to ensure safety during repairs.

2. Clean or Replace Air Filter

Locate the air filter housing.
Remove the air filter and inspect it; replace if dirty or clogged.
Clean the housing and ensure a proper seal when reinstalling the new filter.

3. Clean Throttle Body

Remove the intake duct to access the throttle body.
Use throttle body cleaner and a cloth to gently clean the throttle body inlet and plate.
Ensure the throttle plate opens and closes freely.
Reattach the intake duct securely.

4. Test and Replace Fuel Pump (if necessary)

Connect the fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure.
Compare the reading with the manufacturer’s specifications; replace the fuel pump if the pressure is low.

5. Inspect and Replace Spark Plugs/Ignition Coils

Remove the ignition coils and spark plugs from the engine.
Inspect for wear, carbon buildup, or damage. Replace spark plugs if necessary.
Reinstall the new or cleaned spark plugs, ensuring they are torqued to specifications.

6. Check and Clean Mass Airflow Sensor

Disconnect the MAF sensor connector.
Remove the MAF sensor from the intake.
Use MAF sensor cleaner to clean the sensor elements carefully.
Reinstall the MAF sensor and reconnect the connector.
