Solution

1. Preparation

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

2. Addressing Fuel System Issues

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail test port.
2. Turn the ignition key to the ON position (do not start) and read the pressure. It should be within the manufacturer's specifications.
3. If the pressure is low, inspect the fuel pump and fuel filter for blockages or malfunctions.
4. Replace the fuel filter if clogged and check the fuel pump operation.

3. Cleaning the Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
3. Reinstall the air intake duct securely.

4. Inspecting and Replacing Ignition Components

Sub-steps:
1. Remove the ignition coil covers and inspect the coils and spark plugs.
2. Replace any damaged spark plugs or ignition coils.
3. Reassemble the ignition components and ensure all connections are secure.

5. Cleaning or Replacing the Mass Airflow Sensor

Sub-steps:
1. Disconnect the MAF sensor electrical connector.
2. Remove the MAF sensor from the air intake duct.
3. Clean the sensor using MAF cleaner; do not touch the sensor element.
4. Reinstall the MAF sensor and reconnect the electrical connector.
