I own a 1999 Nissan Maxima GLE and recently had an OBD2 scan performed, which detected fault code P0300. Can someone please explain what this code means and how it affects the vehicle's performance?
The vehicle experiences noticeable missing during acceleration—hesitating when picking up speed. The check engine light is currently illuminated.
