Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a screwdriver or socket set.
Take out the old air filter and inspect it for dirt and debris.
Install a new air filter, ensuring it is seated properly in the housing.
Reattach the air filter housing cover securely.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner onto a clean cloth and wipe the internal surfaces of the throttle body.
Ensure the throttle plate moves freely and is not sticking.
Reattach the intake duct securely.

4. Test and Replace Spark Plugs (if necessary)

Remove the ignition coil cover using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the old plugs for wear, and replace them with new ones if necessary, torquing them to the manufacturer’s specifications (typically around 13 lb-ft).
Reinstall the ignition coils and cover.

5. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter in the fuel line (refer to the manual for the exact location).
Relieve fuel system pressure by removing the fuel cap and using a fuel line tool.
Disconnect the fuel lines and remove the old fuel filter.
Install a new fuel filter, ensuring all connections are secure.
Reconnect the battery and check for leaks.
