    I was thinking that if PCM 2H and APP B are supposed to be grounded but aren’t, then I could conceivably connect 2H to ground manually and see if it makes any difference :) Maybe I’ll try that out tomorrow if it’s not raining too hard.

    Perhaps I damaged a ground wire when I was doing the fuel injector swap and PVC replace. So I’ll also test all of the grounds I see in that region.
