Solution

1. Preparation

Gather all necessary tools and replacement parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Fuel System Inspection and Repair

Remove Fuel Filter
- Locate the fuel filter and relieve fuel pressure by removing the fuel pump relay.
- Disconnect fuel lines using a line wrench, ensuring to catch any spilled fuel.
Inspect and Replace Fuel Pump (if necessary)
- Access the fuel pump by removing the rear seat or accessing the fuel tank from below.
- Disconnect the electrical connector and fuel lines, then remove the pump assembly.
- Install the new fuel pump and reassemble in reverse order.

3. Air Intake System Repair

Clean or Replace Air Filter
- Open the air intake housing and remove the air filter.
- Inspect for dirt and debris; clean with compressed air or replace with a new filter.
Inspect and Replace MAF Sensor (if necessary)
- Disconnect the electrical connector and remove the MAF sensor from the intake duct.
- Clean the sensor with MAF cleaner and reinstall, or replace if faulty.

4. Ignition System Repair

Inspect and Replace Spark Plugs
- Remove ignition coils by unscrewing bolts and disconnecting wiring.
- Use a spark plug socket to remove spark plugs; inspect for wear or damage.
- Install new spark plugs following manufacturer’s torque specifications (typically 13 lb-ft).
Check and Replace Ignition Coils
- Test each coil with a multimeter for continuity.
- Replace any faulty coils, ensuring secure connections.

5. Final Checks

Reconnect the negative battery terminal.
Clear any DTCs using the OBD-II scanner.
Start the engine and let it idle, monitoring for any irregularities.
