When it happens, diagnosing the issue is a pain.
I see people posting similar comments in justification of coil relocation. I'd love to hear the diagnostic procedure that all of these diagnosticians are using that requires more access to the coil than what you already have. If I wanted to go all out with diagnosis for a suspected ignition issue on a DII, I would be using my Picoscope with an inductive pickup on the wires, which wouldn't even require direct access to the coil packs. Without secondary air injection there is plenty of room to access to coil pack connectors or swap individual wires.
Btw, I'm not calling you out specifically, I've seen several others say the same thing and I'm pretty sure most couldn't diagnose a blown fuse
