It’s a manual.

I’m going to pick up those plugs right now and get the NGK(s). The speed works fine. I can ask the previous owner about the diff, but from when I was under the car, it looks like it was never monkeyed with.

I just put the new plugs in and it misses, stalls, hesitates, but won’t throw a code.
