HELP--1990 audi 80 not a quatro 4cyl automatic

[Grant Lenahan]

I believe it is somewhere behind the glove box - if no one knows, I 
could check my old bentley if I can find it.

But first, I'd look for a vacuum leak.

 From the way you wrote this - its unclear what you replaced; what 
tested good; and what you simply say is good.
