I'm hanging my head in shame.

After all the suggestions and diagnostic discussions around my engine
problems - I replaced the ignition wires today and she's running smooth
and the cat isn't glowing.  (Ken's wire swapping suggestion confirmed
the need for new wires - thanks Ken)  Should have done this in the first
place, but somehow the glowing cat and muffler distracted me from the
obvious.  Thanks for all the advice, and sorry for the waste of
bandwidth.

That said; did I fry my catalytic converter during this little episode?
How would I tell, short of removing and inspecting?
