I have been having a rough idle on my '94 3.6, so today I took out the intercooler for the first time and inspected all the vaccum lines AAV among other things. I saw something that left me unsure if it is correct or missing something. I borrowed the picture from the Internet, I have nothing on the threads circled below, not even a screw tapping the hole (although, I tried pushing a wire and seems like it does not go all the way, hence there should be no vaccum leak, but again, I am just not sure).

Looked at the catalog and could not find that something goes there, but still would like some reassurance.

Thanks in advance....
