2016 F150 Spark Plugs

My friends truck was vibrating and had a check engine light on, after using the bluedrive code reader, it showed that Cylinder 3 was miss firing. I inspected the spark plug and it had carbon buildup which prevented it from sparking. Further analysis, I realized that it could be caused by a bad ignition coil.
