Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, screwdriver set, fuel pressure gauge, multimeter, cleaning supplies.
Ensure the vehicle is parked on a flat surface with the engine off and the keys removed.

2. Address Fault Codes

If fault codes are present, note them down.
Clear the codes and perform a test drive to see if the codes reappear.

3. Inspect and Replace Fuel Filter

Sub-steps:
- Locate the fuel filter, typically along the fuel line.
- Use a socket set to remove the filter from the mounting bracket.
- Replace with a new fuel filter, ensuring correct orientation.
- Reconnect fuel lines securely and check for leaks.

4. Clean Throttle Body

Sub-steps:
- Remove the air intake duct connected to the throttle body.
- Use throttle body cleaner and a soft cloth to clean the throttle plate and inside of the throttle body.
- Reassemble the air intake duct ensuring proper fitment.

5. Inspect and Replace Spark Plugs

Sub-steps:
- Remove the ignition coils using a socket set.
- Extract the spark plugs using a spark plug socket.
- Inspect for wear and replace with new spark plugs if necessary, using the manufacturer’s recommended gap.
- Reinstall ignition coils ensuring they are seated properly.

6. Test Fuel Pressure

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition on (do not start the engine) and check for proper fuel pressure.
- If pressure is low, investigate the fuel pump and relay.
