Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts while working on the vehicle.
Raise the vehicle as needed and secure it on jack stands.

2. Addressing Error Codes

Connect the OBD-II scanner and retrieve the stored fault codes.
Document the codes for reference.
Clear the codes and perform a test drive to see if they reappear.

3. Inspect and Clean Air Intake

Remove the air filter and inspect it for dirt and blockages.
If necessary, replace the air filter with a new one.
Check intake hoses for cracks or disconnections and replace if damaged.

4. Fuel System Inspection

Attach a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) and check the fuel pressure reading; it should match the manufacturer's specification.
If pressure is low, check the fuel pump and fuel filter, replacing them as required.

5. Ignition System Check

Remove the spark plugs and inspect them for wear or fouling; replace if necessary.
Test the ignition coils using a multimeter to ensure they are within specifications; replace any faulty coils.

6. Exhaust System Check

Inspect the exhaust system visually for leaks or signs of blockage.
If necessary, repair or replace damaged components, including the catalytic converter if it's obstructed.
