Where can I find a seal for the throttle body connection.

Do you need the gasket or just the O-ring?  I'll be back home after 3:30 and can see what I have.  I'm pretty sure I have a couple of gaskets and I may have an O-ring in my assortment.  I have a loose throttle body that I can use to size it with.

I am on the road till Sunday. Is it just a typical O ring or is it specialized?

It's typical.  The O-ring thickness is 0.10 inches.  The inside diameter is 0.542 inches.  I have a couple if you want me to mail one to you.

Thanks for the offer I really appreciate it. I am in no hurry. I am driving east in Montana right now just outside of Bozeman so nothing happening with the Fiero.

Oring worked. Big Thanks! Idle is around 900 now. There is a voltage issue though. When the radiator fan starts, the idle is drawn down and the engine wants to stall. I am going to check the grounds. Any ideas?

You and MikeMac need to talk.  Both have the same problem.  I keep mine idled at 1000-1100.

I'm curious what would happen if a light bulb was connected in place of the fan.  Would there still be the same drain?  In theory, that would test the wiring.

The same drag on the engine idle occurs when the headlights are turned on. When both lights and fan are on the drag does not double and often if one or the other comes on after the idle has recovered, the drag does not reoccur. This is what got me looking for an idle control issue and not an electrical bug.

Well, you could unplug the IAC to test.  The engine won't run well, and a code will be set, but you can test for any change in the issue.

IAC swap made a noticeable difference if that helps you at all.
