My car misfired on the way home from work yesterday, I pulled over and scanned the codes and it was cylinder 4. Thought it may be my coils since i had changed my plugs ~4k miles ago and idk if the coils were ever changed by the previous owners, so I swapped the coils from cylinder 3 and 4. Took it for ~20-minute drive on the freeway and street and the misfire did not occur. Any idea what the issue could have been? I have a 2hr trip coming up in a couple of days and don't want to risk the misfire coming back on the drive there.
