<VV> idle mixture LM technical spark idea

[Frank DuVal]

To see if one cylinder or more is low on power, and only if stock 
ignition, pull one spark plug wire at a time from the distributor. Note 
if any do NOT change the idle speed. These are the ones not firing or 
not firing well.

Do not keep fingers near distributor tower when pulling the wires. Spark 
can jump over an inch. People with pacemakers be warned-let someone else 
do it.
