I can buy them pretty cheap on the net, but finding a muffler shop to install them might be a problem as they'd want the cat sales too. I really don't blame them, I would too if I were in that business.

My observation is that without the GTP my readings would have been sky high, So I guess the cat's shot.

Does your cat rattle?
thats how my volvos died
they can get clogged I guess

O2 sensors are only good for say 60K miles
so yours night be shot

I don't know if I'd go for the cat first

Well the GTP must have cleaned it out as much as it could but
still can't cure a old part

Good Luck
