Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before beginning work.

2. Replace Air Filter

Remove the air filter housing cover using a screwdriver.
Take out the old air filter and inspect it for dirt and debris.
Install a new air filter, ensuring it fits securely.
Reattach the housing cover and tighten screws.

3. Clean Throttle Body

Locate the throttle body and remove the intake duct using a socket set.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body.
Open the throttle plate and clean both sides thoroughly.
Reassemble the intake duct securely.

4. Test and Replace Fuel Pump (if necessary)

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position without starting the engine, and read the fuel pressure.
If the pressure is below specifications, replace the fuel pump.
To replace, relieve fuel system pressure, disconnect the battery, remove the fuel tank, and replace the fuel pump following the manufacturer's specifications.

5. Inspect and Replace Spark Plugs

Remove ignition coil covers using a socket set.
Disconnect the ignition coils and remove them.
Unscrew the spark plugs using a spark plug socket.
Inspect spark plugs for wear; replace them if necessary.
Reinstall new spark plugs and ignition coils, ensuring they are securely fastened.
