2020 is pretty new but just fyi, I have a 2003 and had the same misfire code and tried swapping coils but it still misfired. After a close inspection I saw that it was the connector to the coil. One of the wires was damaged. The wiring harness on mine doesn't leave much wire to the coil connector, and then they twist them too hard, imo, and wrap them in tape so some of the connectors barely reach the coil. With all of that heat cycling under the hood the wires get brittle. Wouldn't take much of a pull to accidentally damage a connector, the wire or the pin. Could just as easily have been the connector to the fuel injector for that cylinder. Anyway, I got them at a low price on Amazon, all with about 8 inches of pigtail. I replaced the coil connector to the misfiring cylinder and the issue was resolved. Spent an afternoon replacing all of the connectors to the coils and all of the connectors to the fuel injectors, adding a couple inches of wire compared to the original. $35 for the set of coil connectors on Amazon and $12 for the set of fuel injector connectors,
NOTE: MAKE SURE YOU CHECK THE COLORS OF THE WIRES GOING INTO THE CONNECTORS. The new connectors and pigtails are red for positive and black for negative. But the wires in your wire harness are not what you expect. I think on the coil connector the positive wire was green with a white stripe? And I think on the fuel injector connectors they were orange? None of the negative wires were black, although I think they were another color with a faint black line.
