I need to replace one engine coil, I recently had the other two of the three coils replaced by an auto mechanic. I am going to have to replace this coil myself. It is my understanding that the ignition coils on the 2006 KIA supply two spark plugs?

How do you know that is the problem? Were the 3 plug wires replaced that feed the other cylinders?
If you can't find the coils, you can't know it needs the other coil. Which cylinder is giving the problem??
