Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Addressing Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and document any error codes.
Clear the codes and test drive the vehicle to see if the codes reappear.

3. Inspecting the Air Intake System

Remove the air filter and inspect for dirt or blockages.
Check the intake hose for cracks or loose connections.
Replace the air filter if it is dirty.

4. Fuel Pressure Test

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition on (do not start the engine) to check the fuel pressure reading.
If the pressure is lower than specifications, check the fuel pump and fuel filter.

5. Inspecting Ignition Components

Remove spark plugs and inspect for wear or carbon buildup.
Replace any damaged or worn spark plugs.
Test ignition coils for proper function using a multimeter.

6. Exhaust System Inspection

Check for any visible damage or blockages in the exhaust system.
Inspect the catalytic converter for restrictions.
Replace any damaged components as necessary.
