Solution

1. Preparation

Gather tools and parts required for the repair.
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 throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reconnect the air intake duct securely.

3. Replace Spark Plugs (if necessary)

Remove the ignition coil covers (if applicable).
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and replace them with new ones.
Replace spark plugs with the recommended type and torque them to specification (typically around 22 Nm).

4. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter (usually in the fuel tank or along the fuel lines).
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect fuel lines and remove the old fuel filter.
Install the new fuel filter, ensuring proper orientation and tight connections.

5. Reconnect Battery

Reconnect the negative battery terminal.
Clear any stored error codes with the OBD-II scanner.
