Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, fuel pressure gauge
Allow the engine to cool before proceeding with any repairs.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record all stored fault codes and look up their meanings.
Clear the codes and take the vehicle for a test drive to see if they return.

3. Inspect and Repair Components

Gas Cap

Remove the gas cap and inspect for cracks or wear.
Replace the gas cap if damaged or improperly sealing.

Ignition System

Remove ignition coils and inspect for cracks or carbon tracking.
Test the spark plugs for wear; replace if the electrode is worn or damaged.
Reinstall components and ensure they are torqued to manufacturer specifications (typically 15 Nm for spark plugs).

Fuel System

Attach the fuel pressure gauge to the fuel rail.
Start the engine and check the fuel pressure; it should meet manufacturer specifications (typically around 50-60 psi).
If pressure is low, inspect the fuel pump and filter for issues.

4. Final Checks

Reconnect all components securely after inspection and repair.
Run the vehicle and monitor for any abnormal sounds or performance issues.
