Re: O2 Sensors - general

[Jason Douglas <jdouglas@harbor.mitre.org>]

A good standard description of O2 sensors and their automotive 
application may be found in Bentley's book on fuel injection.  The book 
used to be (is?) about $30 and explains how Bosch systems work and how to 
maintain them.

with regard to gas mileage, it depends on the model and year, neither of 
which I saw in your post.  I get around 27 highway, 23 in town with an 86 
5000 with a stick.  The slushbox lowers the numbers by 3-4 mpg.
