Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and parts.
Disconnect the negative battery terminal.

2. Clean or Replace Air Filter

Open the hood and locate the air filter housing.
Remove the air filter cover using a screwdriver (if applicable).
Take out the air filter and inspect for dirt and debris.
Clean the housing with a damp cloth or replace the air filter with a new one.
Reassemble the air filter housing and secure the cover.

3. Check and Replace Fuel Filter

Locate the fuel filter (consult the owner’s manual for its location).
Relieve fuel system pressure by disconnecting the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a line disconnect tool.
Remove the old fuel filter and install a new one, ensuring the correct orientation.
Reconnect the fuel lines and reinstall the fuel pump relay.

4. 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 plate and surrounding areas.
Ensure the throttle plate moves freely without any obstructions.
Reattach the air intake duct securely.

5. Inspect and Replace Spark Plugs

Locate the spark plugs and remove the ignition coils (if necessary) using a socket wrench.
Take out the old spark plugs and inspect for wear or fouling.
Install new spark plugs with the specified gap (consult the owner’s manual for the gap specification).
Reinstall the ignition coils and ensure they are seated properly.
