Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and disconnect the negative battery terminal for safety.

2. Address Fault Codes

Sub-steps:
1. Use the OBD-II scanner to check for any logged fault codes.
2. Record codes and research them to determine the required repairs.

3. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench
Sub-steps:
1. Remove the ignition coils (if applicable).
2. Remove old spark plugs using the spark plug socket.
3. Inspect the old spark plugs for wear and replace with new ones if necessary.
4. Torque new spark plugs to the manufacturer's specifications (typically around 13-15 lb-ft).
5. Reinstall ignition coils securely.

4. Check and Clean the MAF Sensor

Tools Required: MAF sensor cleaner, screwdriver (if needed for removal)
Sub-steps:
1. Disconnect the MAF sensor connector.
2. Remove the MAF sensor from the intake tube.
3. Spray the MAF sensor with MAF cleaner and allow it to dry completely.
4. Reinstall the MAF sensor and reconnect the electrical connector.

5. Inspect Fuel System

Tools Required: Fuel pressure gauge
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition key to the "ON" position (do not start) to check fuel pressure.
3. Compare the reading with manufacturer specifications. Replace fuel filter or fuel pump if pressure is low.

6. Check for Vacuum Leaks

Sub-steps:
1. Visually inspect vacuum hoses for cracks or disconnections.
2. Use a smoke machine or carburetor cleaner to find leaks while the engine is running.
3. Replace any damaged hoses and ensure all connections are tight.
