Is it possible or advisable for me, without the sophisticated CO test
equipment, to try to adjust idle speed and idle enrichment (which changes CO
output)?  Bentley outlines how to do this (I know which screws are involved
and the theory of what they do).  I am wondering if one could tell from only
engine sound and rpm at the tach or with a dwell meter if changing the two
screw adjustments is helping or making the idle run worse?  I live out in
the country and don't have to pass an emissions test, but do want efficient
fuel burn.  I am building a Digitool so should be able to monitor various
engine functions including O2 sensor.

Or is changing the idle values foolish and I should just take my van in to
the dealer for an official adjustment / test, as Bentley describes.

Thanks,
