I tried everything to make that damn code go away for more than a couple hours. Plugs, filters, raise the idle, lower the idle, etc. New oxygen sensors to boot. But alas, I did not want it to be the AMM, but I finally sprung for the $300 and bought one. That little hunk of plastic and wire doesn't look $300 worth but it was the best three hundred I ever spent. CEL gone. More power than I ever remember having. Smother transmission shifts. Off idle hesitation gone. Flutter I had at 2500 rpm, gone. More power, did I mention more power. Apparently I have needed a new AMM for some time.

All in all, if anyone suffers from these ills, the $300 was well worth it. I hated to spend it, but well worth it.
