Changed plugs, wires, fuel filter, no vacuum leaks, no changes.
Does this sound like a particular thing ( cam sensor, injectors, coils?) Thanks

P0300 Random Misfire normally caused by vacuum leaks or bad fuel.

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel
