Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Address Error Codes

If any error codes were retrieved, research and rectify specific issues indicated by the codes.
Clear all codes from the OBD-II scanner.

3. Inspect and Repair Air Intake System

Tools Required: Screwdriver set, vacuum gauge
Inspect the air filter and replace it if dirty.
Check the intake manifold for vacuum leaks and repair any found.
Reinstall and secure all intake components properly.

4. Fuel System Inspection

Tools Required: Fuel pressure gauge, socket set
Connect the fuel pressure gauge to the fuel rail.
Start the engine and check for proper fuel pressure (consult manufacturer specifications).
If pressure is low, replace the fuel pump or check the fuel filter for clogs.

5. Ignition System Repair

Tools Required: Spark plug socket, multimeter
Remove spark plugs and inspect for wear or deposits.
Replace spark plugs if necessary and check ignition coils for proper resistance.
Reinstall plugs and coils securely.

6. Exhaust System Examination

Tools Required: Jack and jack stands, exhaust pipe cutter (if necessary)
Inspect the entire exhaust system for leaks or blockages, particularly in the catalytic converter.
Replace any damaged sections or components as needed.
