Update III:
So I turned the dizzy clockwise about an 1/8 of an inch (I realize that's not much) and drove it. Couldn't get it to highway speeds as it's rush hour around here, but no pinging at WOT. Temp seemed OK, but the idle is still concerning me. It idles about 750/800 in Park, still idles about 550 in gear with my foot on the brake. It sounds like it's gonna fall on it's face, but somehow never does. Should I go after the idle separately?
