Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reinstall the air intake duct and secure it properly.

3. Replace Fuel Filter (if applicable)

Locate the fuel filter (consult the service manual for exact location).
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the old filter (use safety goggles and gloves).
Install the new fuel filter, ensuring all connections are tight.
Reconnect the fuel pump fuse and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coil cover if necessary.
Disconnect the ignition coils from the spark plugs.
Use a spark plug socket to remove and inspect the spark plugs; replace if worn or fouled.
Install new spark plugs to the manufacturer's torque specifications.

5. Clean or Replace MAF Sensor

Remove the MAF sensor from the air intake system.
Use MAF sensor cleaner to clean the sensor element gently.
Allow the sensor to dry completely before reinstalling.
