Guess nobody know’s
I’m not all that familiar with your Probe, but if you have multiple cylinders misfiring, you’re looking for something that is common to all cylinders. What’s common to all four cylinders? Coil? Cap and rotor or center coil wire (although I suspect it’s too new to have those}. It’s probably not fuel related. P0300 would indicate that it’s electrical.
