Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Retrieve Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Follow scanner instructions to retrieve and record any error codes.

3. Inspect and Replace Ignition Components

Spark Plugs:
- Remove the ignition coil using a socket set.
- Extract the spark plug using a spark plug socket.
- Inspect for wear; replace with OEM parts if necessary (Torque to manufacturer specifications).
Ignition Coils:
- If any coil is faulty, replace it with a new one.
- Ensure connections are secure.

4. Check Fuel System

Fuel Injectors:
- Remove the fuel rail (follow manufacturer instructions for disconnection).
- Inspect injectors for clogs; clean or replace if necessary.
Fuel Pressure:
- Use a fuel pressure gauge to check for proper fuel pressure.
- Replace fuel filter if pressure is low.

5. Clean MAF Sensor

Disconnect the MAF sensor wiring harness.
Remove the sensor from the intake duct.
Spray MAF sensor cleaner onto the sensor element; allow it to dry thoroughly before reinstalling.

6. Inspect Vacuum Lines

Visually inspect all vacuum lines for cracks, splits, or disconnections.
Replace any damaged lines.

7. Exhaust System Evaluation

Check for any visible blockages or damage in the exhaust system, including the catalytic converter.
If blockage is found, repair or replace the affected components.
