Unless anyone else has something to add , I think some scope patterns will tell the tale..
Normally, any decent shop would have scoped it from the start, but when we try to do this over the net and in your backyard, sometimes some simple part swaps and look/see stuff works, but sometimes it requires equipment.
You have an ign triggering problem on one coil only and after the few known good part swaps you have done ,that is about all you can do..

I would not drive it with 2 dead jugs....
.. and I have no idea on prices.
