I cleaned and ran it for a few days and it seems to be doing a little better. The thing that I noticed was that when the A/C conpressor would kick on the engine speeded up then went back to normal. It usually speeds up to about 800-900 RPM while in drive. Then when it would kick off, then the engine would go to 400 RPM and then back to normal. But sometimes it would stall. I am thinking the IAC is bad and needs to be replaced.

What are your thoughts?

That is true but it shouldn't make the car stall.

I have had this TB on for about a year now. There is no TPS on this TB.

^^ yeah, there has to be one. Thats the way the ecu knows the throttle position for the right fuel map, and other things.
