Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (refer to the owner’s manual for exact location).
Use a wrench to disconnect the fuel lines from the filter, taking care to collect any spilled fuel.
Remove the old fuel filter and install the new one, ensuring correct orientation.
Reconnect the fuel lines and check for leaks.

3. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle body and the throttle plate.
Ensure the throttle plate moves freely after cleaning.
Reinstall the air intake duct securely.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers (if applicable).
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Install new spark plugs with the correct gap (refer to specifications).
Reinstall the ignition coils and covers.

5. Verify MAF Sensor Functionality

Disconnect the MAF sensor connector.
Inspect the sensor for dirt or damage; clean it with MAF cleaner if necessary.
Reconnect the sensor and ensure it is securely fastened.
