Edit: Thanks XSChtis! I forgot to change multi meter to 20k (doh!) Left is at 8.6k, right is at 8.1k, so they're good.
So TCI box maybe?
I did for fun check one coil with the plug able on and it was 16-17k. Is that normal, too high, too low? As I type I'm thinking I'll try the other, write it down and then maybe do a search on this reading...
