    PO300 is a random or multiple cylinder misfire, it is not assigned to a particular cylinder like a P0301, PO303, PO304 ect which identifies which cylinder is misfiring. A professional grade scan tool offers freeze information as to information valid to when the fault occurs and allows you to read and monitor live sensor data without having to do intrusive testing. The misfire could be caused by too many things either related to ignition components, fuel quality or fuel mixture.
