I've been eye-balling the Durametric for a little while now. Seems like a really useful tool.
I stuffed my big head under the Box last night looking for a ground strap I could clean contacts on. Couldn't find it? Maybe it's on the topside? I'll check that part soon. I've read here and there about ground gremlins causing all sorts of bizzare issues.
AOS tests good (Oil cap test) and is only 4 years old. Never smokes, ever that I've ever seen or could smell. But running a little rich. Could still be 3 bad O2's I guess? It doesn't make sense I couldn't test them, only the one I replaced could I test through the software.
