Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down before working on it.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and replace it with a new one.
Reassemble the air filter housing cover, ensuring a tight seal.

3. Clean Throttle Body

Remove the throttle body from the intake manifold (use a torque wrench to ensure proper reassembly torque).
Spray throttle body cleaner on a clean cloth and wipe the inside of the throttle body to remove carbon deposits.
Reinstall the throttle body, connecting the electrical harness and securing it with bolts.

4. Inspect and Replace Fuel Filter (if applicable)

Locate the fuel filter; refer to the service manual for the exact location.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines (use safety goggles) and replace the fuel filter.
Reconnect fuel lines and replace the fuel pump fuse.

5. Replace Spark Plugs and Ignition Coils

Remove the ignition coil connectors and unscrew the coils from the engine.
Use a spark plug socket to remove old spark plugs and install new ones, ensuring the correct torque specification.
Reinstall the ignition coils and reattach the connectors.
