Just took off the coil pack for cylinder 3 (rear passenger) and removed the spark plug. Plug looked fine, but I got a new OEM one so put it in. Also took off the cylinder 1 (front passenger) coil pack and swapped it with the original cylinder 3 one. Started it up, no change to symptoms. Rough idle/surging. Didn't want to take it for an actual drive. Still showing P0300 and P0303 (I cleared it and it persists, so looks like the coil pack is in the clear).

I have an appointment at the dealer on Monday, but anything else to look at before then? Could it be an injector issue?
