I have no VSV. What does this mean?

[JakeVII]

I have a 1991 3FE FJ80. It has no VSV connected, but everything seems to run okay and I still get about 14 MPG. It has been disconnected since I bought it. I'm sure it was disconnected for a good reason (?). What can I expect if I reattach this? What should I look for before I reattach this?

Hook it up and see what changes. You can always go back and unhook it. Doubt that either way will do any damage.

That's good enough for me.The only question left is "Why would they do this in the first place?"

I'm guessing the PO thought it would make it run better and/or give better mpg?
