I can get an OEM o2 sensor at Advanced for about $80, I might do that. How much can I get an IAC for?

So Justin say's it's the IAC. Where is that located and how simple is it to replace? I might order one and have it meet me in Tennessee.

How hard is it to swap IAC's? It's just the black circular thing with a plug on it right?

Can someone tell me what's going on?

I don't see it on your original post.
I have a TBE w/ test pipe and a UEGO fyi. I'm driving home about 430 miles tomorrow. Will I be fine until I get it fixed when I get home?

Still don't see it.

Nope, not here either.

Common trend here.

Oh, there it is. I never saw this post.
