Found it!!
Don't ask what I had to do in order to use the search function at that other forum. I'm so ashamed, I feel so dirty...

I had an extremely high idle from first startup for about 20 - 30 minutes or so every morning. Turned out to be a bad ECM. Also found the ECM ground was bad, and a new one was run.

..He ran a new ground for the ECM, and then diagnosed it as an ECM problem. I bought one from White Racing Products, put it in.......and the entire car acts differently. My gas mileage went up, secondaries seem to kick in harder, seems to have more power.
