Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth or brush to clean the throttle body thoroughly.
Reattach the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter in the fuel line or under the vehicle.
Use appropriate wrenches to disconnect the fuel lines from the filter.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines carefully and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coils or spark plug wires as necessary.
Use a spark plug socket to remove each spark plug.
Inspect the spark plugs for wear or carbon buildup; replace them if necessary.
Reinstall the new or cleaned spark plugs and reattach the ignition coils or wires.

5. Test and Adjust Throttle Position Sensor (if applicable)

Check the throttle position sensor (TPS) voltage using a multimeter according to the service manual specifications.
If out of spec, replace the TPS and recalibrate as necessary.
