Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during the work.
Allow the engine to cool completely before starting to work.

2. Inspect and Clean the Throttle Body

Remove the air intake duct by loosening the clamps with a socket wrench.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body thoroughly.
Inspect the throttle plate for free movement and ensure it closes completely.
Reattach the air intake duct securely.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter; it is typically along the fuel line.
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the old fuel filter using a line wrench.
Install the new fuel filter, ensuring the fuel flow direction matches the markings.
Reconnect the fuel lines securely.

4. Inspect and Replace Spark Plugs

Remove the ignition coil packs by unbolting them and disconnecting the electrical connectors.
Use a spark plug socket to remove the spark plugs from the engine.
Inspect each spark plug for wear or fouling; replace if necessary.
Install new spark plugs with a gap set to manufacturer specifications (typically around 0.043 inches).
Reinstall the ignition coil packs.

5. Reconnect Battery and Test

Reconnect the battery terminals, ensuring they are tight.
Start the engine and monitor for any abnormal noises or indicators.
