Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, basic hand tools.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting repairs.

2. Address Diagnostic Trouble Codes

Use the OBD-II scanner to retrieve and document any fault codes.
Clear the codes and perform a test drive to see if they return.

3. Fuel System Inspection

Fuel Pressure Check:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "on" position (do not start) and check the pressure reading against manufacturer specifications.
- If low, inspect the fuel pump, fuel filter, and fuel injectors for faults.
Fuel Pump Replacement (if necessary):
- Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.
- Disconnect the battery and remove the fuel tank (if applicable).
- Replace the fuel pump and reassemble the system.

4. Ignition System Repair

Spark Plug and Ignition Coil Inspection:
- Remove spark plug covers and inspect for wear or fouling.
- Replace spark plugs if worn; use the manufacturer-recommended type and gap.
- Test ignition coils with a multimeter and replace any faulty coils.

5. Air Intake System Check

Air Filter Replacement:
- Remove the air filter housing cover and inspect the air filter.
- Replace with a new, clean air filter if dirty or clogged.
Inspect Intake Hoses:
- Check for cracks or loose connections in the hoses.
- Replace any damaged hoses and ensure all connections are secure.
