Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, multimeter, and cleaning supplies.
Ensure the car is parked on a level surface with the engine off and cooled down.

2. Addressing Fuel Pressure Issues

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 the pressure reading.
- Refer to the service manual for the correct pressure specification.
Replace Fuel Filter (if necessary):
- Locate the fuel filter (in-line or integrated).
- Use the socket set to disconnect the fuel lines safely.
- Replace with a new filter, ensuring proper orientation and secure connections.

3. Inspect and Clean Air Filter

Open the air filter housing by removing the clips or screws.
Take out the air filter and inspect it for dirt and clogs.
If dirty, replace it with a new air filter that meets OEM specifications.

4. Replace Spark Plugs

Remove the ignition coil covers (if applicable) using a socket set.
Disconnect the ignition coils and remove the spark plugs using a spark plug socket.
Inspect plugs for wear; replace with new, pre-gapped plugs according to the manufacturer’s specifications.

5. Clean Fuel Injectors

Use a fuel injector cleaning kit with the appropriate cleaning solution.
Disconnect the fuel line and connect the cleaning kit as per manufacturer's instructions.
Run the cleaning process to remove any deposits from the injectors.
