I've never had P0300 come up on any of my vehicles but hopefully this will send you in new directions. Nissan Versa P0300: Engine Misfire Detected | Drivetrain Resource I know some models of the Versa had fuel regulator issues. If that's not the problem I'd try testing the cam/crank sensors and check the EGR system is operating properly. I would think that a cam/crank sensor and probably EGR problems would set other codes as well.

I had to replace the cam sensor on my '02 Ford Escort this summer. I had code P0340 which is a cam position code. There were several drivability issues poor fuel mileage, rough idle and often stalling when stopping at a stop sign/light or when hitting the gas to take off from a stop. After replacing CPS all the drivability issues were gone.

Well, replaced the cam sensor and all the coils just in case. Took it for a drive and thought it might actually be fixed, ran great! then about five miles later I got a check engine light with a P0300 and P0302. Then about a mile later it died and wouldn’t restart. Im about to give up.
Dang, I'm running out of suggestions. I'd go back and check the wiring harness going to #2 to be sure there's not problem there since that's the specific cylinder code it spit out. Might also want to move that coil to another cylinder to be sure the misfire doesn't move. If it does you got a bad coil. If I come up with any other ideas I'll post them. I know you said compression was good but was there any cylinder that was low enough that it might be caused by a bad head gasket and could possibly be the cause of the misfire? Or two side by side cylinders where the compression was lower and the gasket could be bad between those two?
