Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning supplies.
Disconnect the battery to ensure safety during repairs.

2. Address Fault Codes

Connect the OBD-II scanner to retrieve and note any trouble codes.
Clear the codes and start the engine to see if any codes reappear, indicating persistent issues.

3. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter; if dirty, clean it or replace it with a new one.
Reinstall the air filter and housing cover.

4. Test and Replace Fuel Pump (if necessary)

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position (without starting) to check the fuel pressure.
If pressure is below specification, replace the fuel pump:
- Relieve fuel system pressure.
- Disconnect fuel lines and electrical connectors from the fuel pump.
- Remove the fuel pump assembly from the tank and replace it with a new pump.
- Reassemble and reconnect all components.

5. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body and butterfly valve.
Reinstall the intake duct securely.

6. Inspect and Replace Spark Plugs

Remove the ignition coil bolts to access the spark plugs.
Take out the old spark plugs using a socket and replace them with new ones.
Reinstall the ignition coils and secure them with bolts.
