First, thanks for the helpful suggestions.  Now here's scene two - its me
sitting in the back seat with both the Bentley and the Haynes opened up on
my lap realizing I don't own any of the many testing devices mentioned in
either book.  I found the location of the C0 sensor which was mentioned.
Except on my engine, there doesn't seem to be any cap over an adjusting
screw - just seems like a solid piece of alloy to the left of the airflow
meter.I also couldn't locate the ground which was suggested as a possible
cause.
Are these things (ie C0 sensor, airflow) that should be tested or can I
simple play with
an adjusting screw?  (this is my first time dealing with a fuel injection
system)

Any help appreciated-
