Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for dirt or debris.
Install a new air filter ensuring it fits snugly into the housing.
Reattach the air filter housing cover and tighten screws to the manufacturer's specifications.

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 inside of the throttle body until clean.
Ensure the throttle plate moves freely and is not obstructed.
Reinstall the intake duct and secure it properly.

4. Replace Fuel Filter

Locate the fuel filter; consult the service manual for specific location details.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Use a wrench to disconnect the fuel lines from the filter.
Install a new fuel filter, ensuring proper orientation and secure connections.
Reinstall the fuel pump fuse and check for leaks after turning the ignition on.

5. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them with a socket set.
Pull out the old spark plugs using a spark plug socket and inspect them for wear.
Install new spark plugs to the manufacturer's torque specifications.
Reinstall the ignition coils and connect the electrical connectors.
