[s-cars] Stumble/PowerLoss Redux

[Jerry Scott]

Several on the list have mentioned coil failure but you seem to be 
ignoring this suggestion.  This is the most common failure that occurs 
in the ignition system.  If you can find another owner with a proper 
running car. swap out the entire coil group to see if it still 
misfires.  Or, buy  new coils.
