Thanks! How would the exhaust smell (compared to normal) and can you explain "ses from secondary 02s" ( I assume it's something about oxygen sensors). Would mileage be affected?
The dealer wants me to bring it in and check something, as apparently a less significant problem can cause cat testing to appear that it's faulty when it's really not. So, I think I'll do that too before I spend BIG bucks.
