Good news: I found the problem. Nothing’s worse than tearing apart pieces of your car to not find anything. Especially when you’re basing it off a guess. An educated one, but still.

Bad news. There’s oil in the expensive part of the optispark. No (relatively) cheap and easy cap/rotor swap. Oh well. Going to try cleaning it and replacing the oil seal. Might work. Will likely need to spend $500 anyways. In for a penny...

Good news: taking this opportunity to delete the air pump and add new wires/plugs. So much more power. At least 20 internet hp.
