Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine and retrieve any stored error codes.
Note the codes for further diagnosis.

3. Inspect and Replace Ignition Components

Remove the engine cover if applicable.
Spark Plugs:
- Use a socket wrench to remove the spark plugs.
- Inspect for wear or damage; replace if necessary with OEM spec plugs.
- Torque new plugs to manufacturer specifications (typically around 15-20 Nm).
Ignition Coils:
- Disconnect the electrical connectors from the ignition coils.
- Remove the ignition coils using a socket.
- Inspect and replace any faulty coils.

4. Check Fuel System

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition on (do not start) to check the fuel pressure.
- Ensure pressure matches manufacturer's specifications (usually between 3-6 bar).
Inspect for any fuel leaks around the fuel lines and connections.

5. Inspect Intake and Exhaust Systems

Visually inspect the intake manifold for leaks or cracks.
Check the condition of the air filter and replace if dirty.
Inspect the exhaust system for any blockages or damage, including the catalytic converter.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and observe for any warning lights.
