16v Automatic Passat throttle body question for my 8v

[kervinridgley at earthlink.net (Kervin)]

I re-did my tests with a proper connector on the tps and all is will.  My
readings were just a little different from Mark's - 3.07 to 1.08 so all is
well.  Thanks Mark and Dan, I do still need to think through how the idle
gets adjusted with out an idle screw, but I'm moving so slow on this project
that it won't come up for a while.
