Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on level ground and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Replace Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing cover.
Take out the old air filter and inspect for dirt or damage.
Install a new, clean air filter and reassemble the housing.

3. Check and Replace Fuel Filter

Locate the fuel filter (check the owner’s manual for the exact location).
Relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a fuel line disconnect tool.
Replace the old filter with a new one, ensuring correct orientation.
Reconnect the fuel lines and reinsert the fuel pump fuse.

4. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body internally, removing carbon deposits.
Reassemble the air intake duct.

5. Inspect and Replace Spark Plugs

Remove the ignition coil by unscrewing it and disconnecting the electrical connector.
Unscrew the spark plug using a spark plug socket and ratchet.
Inspect the old spark plug for wear; replace with new spark plugs as needed.
Reinstall the ignition coil and reconnect the electrical connector.
