Jarrod,

i think i have a similar problem. i have civic LX 99 and my check engine lamp came up. i went to go check and the dealer told me that i have a crack on catalytic converter and that my o2 sensor is broken. To fix that, they said it'd cost $845 total (catalytic converter ($585), O2 sensor ($150), labor ($110)). My car has 67,000 miles right now.

Would this be covered under "emission warranty" to replace all these, too? Or is it different thing? it's be so nice if i can get that for free. If not, you think that quote is pretty good price?
Thanks!
