My 2015 fit with 142k is getting a misfire code for cylinder 4 and has a slight shake at idle but runs and drives fine and has plenty of power. I swapped the #3 and #4 cylinder ignition coil but it still has misfire in cylinder 4. What could be causing this.
What are all the codes?

Bad spark plug or a partially clogged injector.

When was the last time you had it serviced (and a basic tune up)? Have the valves ever been adjusted?
