What is the code?
If it is for the rear catalyst then your just looking at a new rear o2 sensor

Sweet... bring it to a dealer. Cat is warranteed for at least 80K unlimited years. Or is it 120K? Either way..

^i thought it was only the 01 to 02 under 120k?

i bought it used from carmax though, does that matter? when we checked with carmax they said they dont do cats in their garage. i also was told that pontiac dealerships have closed or been bought out or something.

No..it doesn't matter. Car manufacturers had problems with emissions equipment in the beginning and the public was outraged by the cost of a catalytic converter. So the EPA mandated that all car manufacturers had to warranty the cats to at least 80K miles.
My truck got all 4 new cats for free at about 75K miles. And ...then I er uh bought a new o2 sensor..lol
