Vacuum line from throttle body plugged

I just noticed on my 97 'Bird (3.8L) that the large vac line coming off the throttle body that goes to the purge valve has been cut and plugged with a bolt. I have no issues with how the car runs so my question is what is the significance of someone having done this? Is it causing any loss of power that I may not be aware of, or is it purely emission-related? If it's the latter, then I'm not terribly worried about it as I'm not subject to emissions testing nor am I a hippy.

Wow. A week and literally nobody knows the significance of having that vacuum line plugged.

its also possible that no one saw this post... they sometimes get lost in cyberspace.

I would recommend reattaching it to the throttle body. I can't imagine why it would have been blocked off, but it is supposed to help fuel economy. I don't know if that affects the power output much, but its supposed to help you get better mileage.

Thanks. It actually has a piece of hose 5" or so long attached with a bolt in it. I don't know where the hose is supposed to go.

Isn't there a vacuum diagram under the hood?
It most likely goes to the purge solenoid.

there should be a bung on the throttle body, passenger side.

Obviously. That's where the hose with the bolt is connected. Where is the purge solenoid actually located?

here is what it should look like the pipe heading alongside the fuel rail is the one that attaches to the throttle body
