I have replaced the Idle Air Bypass
Cleaned the ACT, Mass Air filiments
tested the temp sensor at 180* it reads the right ohms (as per a Chilton manual)
I should probably check it cold and clean Pin 10 as suggested in this thread.

What else should I be looking at?

I bought a car that wouldn't start until about the third time. Then it would not have the fast idle after it finally started. It turned out to be the computer. It had a Cobra computer. The Cobra computer is set up a little different.
