Resolved CubCrafters Lycoming cc363i erratic RPM and now running rough on R lightspeed ignition

That is crazy that it would happen again to the same coil pack! Very odd. Something to keep a double check on for sure.

I’m hoping this is the lone original coil pack. Three were replaced.

It was a bad coil pack. Ohm test at 3 Kohm, normal is 16. It was a new coil pack from lightspeed date code 0824 from last November. As two I pulled that were original and I marked “likely good” ohm checked good and installed instead of another new one just because I think it’s still good. Engine run tests perfect. IA was on board for verification and sign off with treat bribes. Obviously mutt muffs are not working. Trying her with the new Rex specs hearing protection for dogs. I think the one I got is too small so tried these again. I digress.

Approximately 1.5 hours to decowl and replace coil pack. Now to reassemble
