One more WB

[Scot Sealander]

One more DIY wide-band that works, at least in free air it reads 3.88
volts.  It did have a problem at first power on.  I powered it up the
first time without the sensor hooked up.  The "sensor warm" LED
immediately came on, but the voltage regulator was only putting out 3.42
volts into an open circuit.  Investigation showed that the LM431 in the
voltage regulator circuit was bad as installed.  Replaced the LM431, and
all is well.

The code has been added to the ECM, it re-assembles w/o error, so it
will probably go in the car tommorrow after work... Looking foward to
see what it does!
