Does anyone know if that can be done?
I would take what Steve T recommended and take it a step further by moving the plug and the coil pack to different cylinders to isolate whether it is the plug or the coil.

Since you have the Durametric tool, you should be able to read the freeze frame data that was captured when the CEL came on (especially for misfire faults). If you can retrieve this data, please post it as it can help us help you. I'm particularly interested to see how the fuel adaptation is working.
