Was putting the top end back together, using photos and white out spots for reference I now notice that this didn't have a vacuum line attached previous to my taking things apart either. Appears to have gotten it from the PO without also. Can't find on vacuum diagram or in the FSM

I will have to look later .

There may not be anything attached to that nipple

 

That's what I was thinking but I thought I'd ask before I left it that way..

 

All I know about it is that it's a VSV. If it's the one I'm thinking of part of it has fallen off or broke, I don't know if would still work correctly or not.

"Shot of the idle-up valve and the A/C VSV that turns on w/ A/C operation to boost idle speed."

So at some time the filter broke and fell off.

I am sure with a little thinking something can be found to work

All it does is keep more junk from being pulled into the engine.

 

So it's a filter, didn't know that.
