Alright, so I went to my oil changing shop today and they used the scanner to detect anything, but only the o2 sensor popped up at first. After they did the fuel injector cleaner, they used the scanner again and the o2 sensors popped up again, but then P0304 popped, but they said that’s normal because the car is not used to having that stuff in its system or something like that. I’m here to just ask is that normal?

No that's not at all normal for a vehicle to all of a sudden start having issues after a fuel injector flush. The only issue it may have is a bit of a rough idle as the injector flusher runs out of the solution, the vehicle will stumble and stall. But after the fuel pump is re-connected all should be well, possibly setting a code or 2 but should run good after these codes are cleared. What O2 code popped up?
