Fixes:
- Replace worn or leaking valve cover gaskets to stop oil leaks
- Renew ignition coils and spark plugs to resolve misfires and rough idling
- Repair or replace faulty fuel injectors if fuel delivery issues are detected
- Service or replace the turbocharger if boost pressure is inconsistent or if mechanical damage is found
