Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery before starting any electrical work.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Clean Air Intake System

Remove the air filter and inspect for dirt or blockages.
Clean or replace the air filter as necessary.
Inspect the intake ductwork for cracks or loose connections and replace if needed.

3. Check and Replace Fuel Filter

Locate the fuel filter and relieve fuel system pressure.
Disconnect the fuel lines from the filter using a line removal tool.
Install the new fuel filter, ensuring all connections are secure and leak-free.

4. Replace Spark Plugs

Remove the ignition coils by unscrewing them and gently pulling them out.
Use a spark plug socket to remove old spark plugs.
Gap the new spark plugs to manufacturer specifications and install them.
Reattach the ignition coils.

5. Clean Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft brush to clean the throttle plate and bore.
Reinstall the throttle body, ensuring the gasket is in good condition.

6. Reconnect Battery

Reconnect the battery terminals securely.
Clear any error codes stored in the ECU using the OBD-II scanner.
