Be nice if you had the specific code. That car is plagued with P0420 codes which were tied to the secondary O2 sensor reading out of range. On rare occasion it was the O2 sensor, sometimes it was the catalytic converter and usually you were just screwed. Had a lot to do with the emissions on the car being wound up as tight as they could so it would get a ULEV classification. As the car aged and the motor fully breaks in the overall emission output of the vehicle starts to increase even with all the proper control systems in place and working as they should. If that is the code you have and you do not live in an emissions check area and your fuel mileage is not negatively impacted it may be best to ignore it.
