Solution

1. Preparation

Gather tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety.

2. Replace Air Filter

Remove the air filter cover using the appropriate socket or screwdriver.
Take out the old air filter and inspect it for dirt or damage.
Insert a new air filter that matches the OEM specifications.
Reattach the air filter cover securely.

3. Check and Replace Fuel Pump

Access the fuel pump by removing the rear seat or fuel pump access panel.
Disconnect the electrical connector and fuel lines from the pump.
Remove the fuel pump assembly using a socket set, noting the orientation.
Install a new fuel pump, ensuring it is seated correctly.
Reconnect the fuel lines and electrical connectors, then reassemble the access panel.

4. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them and disconnecting the electrical connectors.
Use a spark plug socket to remove old spark plugs from the cylinder head.
Check the gap on new spark plugs and install them to the manufacturer's specifications (usually around 0.044 inches).
Reinstall the ignition coils and reconnect the electrical connectors.

5. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Ensure no cleaner residue remains before reassembling the intake duct.
