Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cold.
Disconnect the battery to avoid electrical shorts.

2. Address Diagnostic Trouble Codes (DTCs)

Connect the OBD-II scanner and note all retrieved codes.
Research codes and determine which components may need testing or replacement.

3. Inspect and Repair Fuel System

Remove the fuel pump fuse and relieve fuel pressure.
Check fuel lines for leaks and repair as necessary.
Replace the fuel filter if clogged and check the fuel pump operation using a fuel pressure gauge.

4. Clean or Replace Air Intake Components

Inspect the air filter; replace it if dirty.
Remove the intake duct and clean the throttle body with throttle body cleaner.
Ensure the Mass Air Flow (MAF) sensor is clean; if necessary, use MAF cleaner.

5. Check Ignition System

Remove spark plugs and inspect for wear; replace if necessary.
Test ignition coils with a multimeter; replace any that are out of specification.
Reinstall components and ensure all connections are secure.

6. Inspect Exhaust System

Visually inspect the exhaust for signs of damage or blockages.
If needed, remove the catalytic converter and check for internal failure.
