Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, basic hand tools.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is on a level surface and the engine is cool.

2. Addressing Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port and retrieve the stored trouble codes.
Compare the codes with manufacturer specifications to determine the underlying issue.
Clear the codes and monitor if they reappear after a test drive.

3. Inspect and Replace Components

Ignition System:
- Remove the engine cover if applicable.
- Disconnect the ignition coils and inspect for cracks or carbon tracking.
- Remove and inspect spark plugs; replace if worn or fouled. Torque to manufacturer specifications (typically 15-20 Nm for Volvo).
Air Filter:
- Open the air filter housing and remove the air filter.
- Replace the air filter if dirty or clogged.

4. Check Fuel System

Inspect fuel lines and connections for leaks or damage.
Replace the fuel filter if the vehicle is due for maintenance or if fuel pressure tests indicate a restriction.

5. Reassemble and Test

Reconnect all components and ensure all connections are secure.
Reconnect the negative battery terminal.
Start the engine and check for any abnormal noises or persistent warning lights.
