Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, and cloth.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body and use a soft brush to remove any carbon deposits.
Wipe the throttle body clean with a cloth.
Reattach the air intake duct securely.

3. Replace Spark Plugs

Tools Required: Socket set, torque wrench, and spark plug gap tool.
Remove the ignition coil cover (if applicable) to access the spark plugs.
Detach the ignition coils and remove the old spark plugs using a spark plug socket.
Check the gap on the new spark plugs and install them, torquing to the manufacturer’s specifications (usually around 13 lb-ft).
Reinstall the ignition coils and cover.

4. Inspect and Replace Fuel Filter

Tools Required: Fuel line disconnect tool, socket set, and a catch pan for fuel.
Locate the fuel filter; it's typically found along the fuel line.
Relieve fuel pressure from the system (consult the service manual for the procedure).
Disconnect the fuel lines using the fuel line disconnect tool.
Remove and replace the old fuel filter with a new one, ensuring the flow direction matches the markings.
Reconnect the fuel lines securely and check for leaks.

5. Check and Clean the Mass Airflow Sensor

Tools Required: MAF sensor cleaner.
Disconnect the electrical connector from the MAF sensor.
Remove the MAF sensor from the air intake duct.
Spray MAF sensor cleaner onto the sensor elements and allow it to dry completely.
Reinstall the MAF sensor and reconnect the electrical connector.
