Solution

1. Preparation

Gather tools and parts. Disconnect the negative battery terminal to ensure safety.
Tools required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, torque wrench.

2. Check and Replace Fuel Filter

Sub-steps:
1. Locate the fuel filter (usually near the fuel tank).
2. Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
3. Disconnect the fuel lines from the filter using a line wrench.
4. Remove the fuel filter retaining bracket and take out the old filter.
5. Install the new fuel filter, ensuring the flow direction matches the markings.
6. Reconnect the fuel lines and secure them.

3. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil cover to access the spark plugs.
2. Disconnect the ignition coils from the spark plugs.
3. Use a spark plug socket to remove the old spark plugs.
4. Inspect the spark plugs for wear; replace if necessary.
5. Gap the new spark plugs to manufacturer's specifications and install them.
6. Reattach the ignition coils and cover.

4. Inspect and Clean the Throttle Body

Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
3. Ensure the throttle plate moves freely and is not sticking.
4. Reinstall the air intake duct securely.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear any diagnostic trouble codes.
3. Start the engine and monitor for any abnormal behaviors.
