Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before starting work on the vehicle.

2. Check Fuel System

Tools Required: Fuel pressure gauge, wrench set
- Remove the fuel pump relay from the fuse box.
- Connect the fuel pressure gauge to the fuel rail.
- Reinstall the fuel pump relay, start the engine, and observe the pressure reading.
- If pressure is below specification, replace the fuel pump.

3. Inspect Air Intake System

Tools Required: Screwdriver set, flashlight
- Visually inspect the air filter for dirt and clogging; replace if necessary.
- Check the intake hoses for cracks or disconnections, and replace any damaged components.
- Ensure the mass airflow sensor (MAF) is clean and functioning; clean it with MAF cleaner if needed.

4. Examine Ignition Components

Tools Required: Socket set, multimeter
- Remove the ignition coils and inspect for cracks or corrosion.
- Use a multimeter to check the resistance of the ignition coils; replace any that are out of specification.
- Remove spark plugs and inspect for wear or fouling; replace if necessary.

5. Reset Engine Control Unit (ECU)

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and let it idle to ensure the problem is resolved.
