I would first try the ECU relearn procedure. I doubt the dealer went ahead and did that after replacing everything, that should be your first step.

I also have a 2014 WRX and had the same error code. I brought it in this morning and this is the second 2014 WRX that had this issue (the other WRX had been in 2 or 3 times so far and was there today). The dealer contacted the Subaru tech line and the few items they had them check out were okay. They cleared the codes and basically told me to notify them if it comes back. Looks like I might be starting a similar cycle.

My 2014 wrx threw a cel and cruise and had rough idle. I replaced the O2 sensor with a Bosch O2 sensor. Problem went away and came back. Then I replaced with OEM O2 sensor and problem went away.

Have you guys checked the intake manifold gaskets for leaks? There was an issue circulating on the forums a couple years ago about bad gaskets causing rough idle and CEL's. Might be worth checking for vacuum leaks. I'd also suggest plugging in an OBD logger to see what your fuel ratios and timing advance are while it's idling. Some data logging may give us clues to the issue.
