Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure the engine is cool before starting work.

2. Air Filter Replacement

Remove the air intake duct by loosening the clamps using a socket set.
Take out the air filter from the airbox and inspect it for dirt or blockages.
Replace with a new air filter, ensuring it fits snugly in the airbox.
Reattach the intake duct and secure with clamps.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "On" position without starting the engine to check pressure; it should be within manufacturer specifications.
If pressure is low, replace the fuel filter and inspect the fuel pump for functionality.
Reconnect any lines and ensure there are no leaks.

4. Spark Plug Inspection and Replacement

Remove the ignition coil cover using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Remove the spark plugs using a spark plug socket and inspect for wear or fouling.
Replace with new spark plugs that meet OEM specifications.
Reinstall the ignition coils and cover securely.

5. Throttle Body Cleaning

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean any carbon buildup inside the throttle body.
Reattach the air intake duct and ensure it is secure.
