Too bad you failed by such a miniscule amount, but a fail is a fail. How messed up were the plug wires? Misfiring on account of bad plugs, wires, rotor or cap could definitely give you a high HC reading, though it could well be the cat. If it's the original cat, you're lucky it lasted this long.
Yep, it doesn't take very long running rich or misfiring to wreck a new cat.
