Yeah but it's less likely on a '14 FR-S unless it's crazy high mileage and past due for a valve adjustment.
It's was a bad batch of engines in 17 and 18 that were adjusted too tight. But if a few thousands on a valve shim can trigger these codes... anything could...
Typically, it seems like the engines with tight valves would throw the codes but still run right. mine was like that: If I wanted it to set it had to be in extremely specific conditions of warming up from 10-12 degrees celcius, with the water temp up to 50-55C, at idle with no electrical loads or AC, it would idle ever so slightly uneven for those 40 seconds where everything was perfect and it'd store the code. Just having the lights on would put enough load on the engine to make the problem go away.
If you've got a cylinder constantly missing, then it should be easy to find the culprit.
