The car runs fine when the O2 sensor isn't hooked up, so I don't have any
vaccuum leaks, and the VW tuner played with the fuel mixture/idle speed
for an hour on Monday and told me I would probably have to replace the
ECU and some wiring.  I'm trying to be 100% sure that this is what I have
to do before I spend money on it.
