Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery negative terminal to ensure safety during the repair process.

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 debris.
• Install a new air filter, ensuring it fits securely, and replace the housing cover.

3. Fuel System Inspection

• Connect a fuel pressure gauge to the fuel rail service port.
• Turn the ignition key to the "ON" position (do not start the engine) to check the pressure reading.
• If pressure is low, replace the fuel pump and filter as needed.
• After replacement, re-check fuel pressure to ensure it is within specifications.

4. Throttle Body Cleaning

• Remove the intake duct connected to the throttle body after disconnecting any sensors.
• Use throttle body cleaner and a clean cloth to remove carbon build-up inside the throttle body.
• Reinstall the intake duct securely and reconnect any sensors.

5. Ignition Component Replacement

• Remove the engine cover if applicable.
• Disconnect the ignition coil connectors and remove the coils using a socket set.
• Replace worn spark plugs and ignition coils with new components.
• Reinstall coils and engine cover.

6. MAF Sensor Cleaning

• Locate the MAF sensor in the intake system.
• Disconnect the electrical connector and carefully remove the sensor.
• Use MAF cleaner to clean the sensor element and allow it to dry before reinstalling it.
