Bypass Valve(maybe)

There is a vacuum line about 6-8 inches long that runs between to sections of the intake plenum, at least on 89-90's I seem to remember some little trick of cutting that hose and blocking off both ends. I know most of us did it back when, only I don't recall WHY we did it.

Anyone remember?

Thanks folks
 
That would be it KMT sounds like it really does ZIP, we used think it did. Doesn't seem like it causes any harm but doesn't seem to much good either.

Thanks for finding that, much appreciated.
