If there is a vacuum leak (which can cause misfires) then it would most likely show a code for o2 sensor out of range, limit exceeded.....i forget the p code for that......

If just the misfire code on #4 I would first swap the #4 coil with cylinder 6 as it's easy to get to......then see if the misfire stays.
Id the coils are new there is the possibility the connector isn't” clicked” onto the coil properly, why were the coils replaced?
