Hmmm OK so it's not an imperfect timing issue. I'm continuing to have a rough running engine during idle. I've readjusted my fast idle adjustment as per the book and when I start the engine cold it idles way to slow (under 500 RPM). When warm it runs as it should (acceleration and idle are fairly normal though not perfect) and drives OK. One thing I know is an issue is that my Anti Backfire valve doesn't work correctly. It seems to be pulling air full time from the air-cleaner, as in, it's a huge vacuum leak and causes massive fuel use. Since I can't find a new one I've done a temp fix by blocking the port with duct tape until I do find a replacement.
Beyond that though, My focus is becoming the Fast Idle Control Device or F.I.C.D. I'll be checking my codes this afternoon since I've driven it enough for it to have set codes if it's an electronic problem.
