Flipped manifolds overheated my coils, didn't know they were so sensitive, ran really weird, breaking up worse and worse over time. I thought it was grounds but swapping out to another set of coils fixed it.

Any way to tell which coils are shot and which can be reused? They all seem to ohm the same across the two terminals that actually read anything.

You can use an adjustable gap spark tester and hook each one up and see if it will fire. Probably want about an inch gap set on the tester.

Or a current clamp meter via a scope should tell you which coils are charging correctly or not
