Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Inspect and Replace Fuel Filter

Sub-steps:
1. Locate the fuel filter (typically found along the fuel line).
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect the fuel lines from the filter using a wrench.
4. Remove the old fuel filter and replace it with a new one, ensuring proper orientation.
5. Reconnect the fuel lines securely.
Tools Required: Wrench set, fuel line disconnect tool.

3. Check and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if necessary 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 old plugs for wear and gap; replace with new plugs as needed, ensuring correct gap specifications.
5. Reinstall the ignition coils and engine cover.
Tools Required: Spark plug socket, torque wrench.

4. Test and Replace Throttle Position Sensor (if needed)

Sub-steps:
1. Locate the throttle position sensor and disconnect the electrical connector.
2. Use a multimeter to test the resistance values of the TPS.
3. If readings are outside specified ranges, remove the sensor and install a new one.
4. Reconnect the electrical connector and clear any error codes.
Tools Required: Multimeter, screwdriver set.
