The Dreaded P0420 Code
The Teg threw a random code while driving today -- P0420 (unexpected oxy sensor readings, bad cat, etc.)
It hasn't popped back up, but I'm starting to worry if the cat is going bad. Not a cheap fix... 140K miles -- is this a reasonable amount of time (what's the average?) Could be a sensor...
Hopefully it was an EOC fluke (crosses fingers).
