[V8] 91 V8 5 spd - Intake air leaks

[dsaad at icehouse.net]

To find the box (I think it is really called the A/C Programmer), just follow
the bundle of colored vacuum hoses in the passenger side footwell. It won't be
hard to find.
Don't be shocked when you find the "Delco" label on it either - it is in fact
made in the good ole USA.

Of course that is history now too - since Delco turned into Delphi which is
turning into yet another opportunity for the Chinese to make money.
