If all else fails you can get a computer reflash (depending on your year) which will disable the rear 02 DTC check.
Thanks for the help. I am logged in under a new username with a signature now. regarding a computer reflash: I currently have the car at a dealership service dept.--Are they able to handle a reflash or is it something I can learn about?
They have told me that the CAT itself is bad (but it is brand new). I installed it myself and created the prblem by not using the 50 state model . After almost $2500 in a bunch of front end parts,new tires, new motor mounts, etc. I got cheap on the cat and can't get a sticker !! Bummer!
