FINALLY GOT MY CAR BACK WAHOOO!!!!.

For those who dont know, i got into a accident and my left corner of the car was pretty messed up. What sucked the most is that my dampner was damanged and well since Tein didnt have a distributor here with parts at the time, i had to order and wait... Anyway got the car back tonight (Thank God) and well everything seams A-OK except my exhaust smells like rotton eggs. I know that this is because the fuel is staying in the cat because i'm running rich and all. And i know this because i fail'd smog a 3 1/2 months ago. I think my o2 sensor has gone lazy and now i'm hopping it hasnt ruined the cat. If it smells like this is it done for? Am i going to need a new cat?

Blah, anybody got any extra o2 sensors or somthing they would like to sell. New or used, i'm just looking around.
