Question

how to find out where the proble is a sencer or a contion or something else.

Answer 1

P0300 Random misfire

Very small chance this would be caused by a sensor, but more of a condition, You have component such as the ignition coil , the sparkplug wires, that are mostly the main cause for a P0300. A good look into the spark plug and the condition would give you the best direction to go by.
