Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Address Engine Codes

Use the OBD-II scanner to retrieve and note the trouble codes.
Research the codes to determine the affected system or component.

3. Inspect and Clean the Air Intake

Remove the air filter and inspect it for dirt or damage.
Clean the air intake duct and throttle body using throttle body cleaner.
Reinstall the air filter or replace it if necessary.

4. Check Fuel System

Connect a fuel pressure gauge to the fuel rail and check the pressure against manufacturer specifications.
If pressure is low, inspect the fuel pump and filter for issues and replace them if necessary.

5. Examine Ignition System

Remove spark plugs and inspect for wear or fouling.
Replace spark plugs if they show signs of damage.
Test ignition coils for proper resistance; replace any faulty coils.

6. Inspect Exhaust System

Visually inspect the exhaust system for leaks or blockages.
If necessary, check the condition of the catalytic converter; replace if damaged or restricted.

7. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the trouble codes and reset the check engine light.
