Clear the codes to see if they return after a test drive.

3. Inspect and Replace Faulty Components

Ignition System:
- Remove the engine cover (if applicable).
- Inspect spark plugs for wear or damage; replace if necessary (torque to manufacturer's specification).
- Check ignition coils for cracks and proper operation; replace faulty coils.
Fuel System:
- Inspect fuel injectors for clogs; use a fuel injector cleaning kit if necessary.
- Check fuel pressure with a fuel pressure gauge; replace the fuel filter if pressure is low.
Air Intake System:
- Remove and inspect the air filter; replace if dirty or clogged.
- Inspect intake hoses for cracks or loose connections; replace as needed.

4. Reassemble and Test

Reconnect any components that were removed during inspection.
Reconnect the battery and start the engine, monitoring for any unusual sounds or warning lights.
