Never mind about the last post.
I have tryed a couple of things:
1)First I tried to bypass the IAC, making sure there was no air leak.
With this configuration, as Axe just said the engine wouldn't idle and after revving up, it would run at high RPM. I also got some backfiring.

2) I tryed to Isolate the hose opening. Didn't work either. No idle at all and again, some backfire when I rev up.

Something that I didnt'try (and I should've) is disconnect the IAC connector with the engine in Idle.

I'll take some more picts showing details of the other red arrow. It seems like an yellow box with some thin hoses. I'll take detailed pictures tomorrow.
