I have a '99 Miata with 65K miles. Bought it used @ 32K in 2001. The Catayltic Converter was replaced just before the purchase. A week ago the P0420 code showed up. I replaced the plugs and wires. The code didn't reappear for another few days (30 miles). What's the next step? Isn't there a way to better pin-point the problem (Cat, O2 sensors, Coil ...).
Anyone in the Plano area you recommend that can help in understanding and fixing?
Thanks,

I think the first step is to check out your O2 sensors.
If you want someone to work on it for you, send a PM to Rogue (on the forum here).
Here is some info from OBD-Codes.com

Miata tecnologies (on the web) Tom has been into miatas a long time. He put in a clutch,crankshaft positioning sensor, and front wheel hub along with some tune up stuff, at reasonable prices. Good Luck, JonlouieQuote:

Call Rogue.
Or a spastic, blind, crack monkey.
But Rogue does better work ;)
I just had this same issue:

Do you notice your car running rich?
Here is probably the fix for you.
$47 in parts and about 2 hours of work.
