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.

As Frank mentions - please do not do this unless you are running a stock,  
point-type distributor. If you are running any type of Electronics INSIDE the  
distributor cap, the removal of a wire can cause the spark to jump to a ground  
inside the cap, which might easily be a part of the ignition pieces inside.  
Instant dead electronics can result. - Seth
