Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, throttle body cleaner, cleaning brushes.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery to prevent electrical shorts.

2. Address Error Codes

Use the OBD-II scanner to retrieve and document any error codes.
Clear the error codes and monitor if they return after a short test drive.

3. Fuel System Inspection

Check Fuel Pressure:
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position without starting the engine and check for proper fuel pressure (consult service manual for specifications).
- If pressure is low, inspect the fuel pump and filter for issues.
Replace Fuel Filter if clogged.

4. Ignition System Service

Inspect Spark Plugs:
- Remove spark plugs using a socket wrench.
- Check for wear and carbon buildup. Replace if necessary.
Test Ignition Coils with a multimeter to ensure they are within specifications. Replace faulty coils.

5. Throttle Body Cleaning

Remove Throttle Body:
- Disconnect the throttle body’s electrical connector and remove the mounting bolts.
- Gently pull the throttle body away from the intake manifold.
Clean Throttle Body:
- Use throttle body cleaner and a soft brush to clean carbon deposits.
- Reinstall the throttle body and reconnect the electrical connector.

6. Final Checks and Reassembly

Reconnect the battery and start the engine to ensure it runs smoothly.
Monitor for any signs of stalling or error codes after the repairs.
