Solution

1. Preparation

Gather tools and parts required for the repair.
Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, cleaning supplies (e.g., throttle body cleaner).
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Address Fault Codes

Use the OBD-II scanner to retrieve and document error codes.
Clear the codes and perform a test drive to see if the codes reappear.

3. Inspect and Clean Components

Throttle Body Cleaning:
- Disconnect the negative battery terminal.
- Remove the air intake duct to access the throttle body.
- Spray throttle body cleaner into the throttle body and wipe with a clean cloth.
- Reassemble the air intake duct and reconnect the battery terminal.
MAF Sensor Cleaning:
- Disconnect the MAF sensor connector.
- Remove the MAF sensor from the intake manifold.
- Spray MAF cleaner on the sensor elements (do not touch them) and let dry before reinstalling.

4. Check and Replace Spark Plugs

Remove the ignition coil packs using a socket set.
Extract the spark plugs using a spark plug socket.
Inspect for damage and replace with new spark plugs if necessary (ensure correct gap size).
Reinstall the ignition coil packs and ensure they are seated properly.

5. Test Fuel System

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start the engine) and check for proper fuel pressure (refer to manufacturer specifications).
If pressure is low, inspect the fuel pump and filter for issues.
