Solution

1. Preparation

Gather tools and parts, ensuring you have an OBD-II scanner, socket set, and basic hand tools.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Fault Codes

Use the OBD-II scanner to read any diagnostic trouble codes (DTCs).
Write down the codes for reference; clear them after repairs are completed.

3. Inspect and Replace Fuel Filter (if necessary)

Sub-steps:
- Locate the fuel filter (typically near the fuel tank).
- Use the appropriate socket to remove the mounting bracket and disconnect fuel lines.
- Install the new filter in the correct orientation and reconnect the lines.
- Ensure all connections are secure and check for leaks before reattaching the bracket.

4. Clean or Replace Spark Plugs

Sub-steps:
- Remove the ignition coil cover if applicable, then disconnect the ignition coils.
- Unscrew the spark plugs using a spark plug socket.
- Inspect the plugs for wear; clean or replace them as necessary.
- Reinstall the spark plugs and reconnect the ignition coils.

5. Throttle Body Cleaning

Sub-steps:
- Remove the air intake hose connected to the throttle body.
- Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
- Reassemble the intake hose securely.

6. Final Assembly and Testing

Reconnect the battery.
Start the engine and let it idle, monitoring for any irregularities.
Conduct a test drive to assess performance under various driving conditions.
