Hi I’m Dan, bought an 2011 ex35 off auction for 4k, had some minor radio problems thag didn’t allow the vehicle to start, now having a CEL and car doesn’t go above 50mph without shaking, Ran the code P0300 and P0304, was thinking possibly a sensor or injectors (changed sparks less then 5k miles ago)

I would start with moving the coil from the #4 cylinder and swapping it with another cylinder. Clear codes and drive the car. See if the code(s) come back, and see if the P0304 changed to a different code (P0301,P0302,P0303...etc.) If that is the case, I would say your coil is bad and needs to be replaced. Replace with OEM, as aftermarket coils have a higher failure rate.
