Winter is coming and my 05 keeps on throwing "cat deficiency" code. And disabling most of safety features of the car while at... Where can i get an O2 sim for the rear. Moderately priced (I think its a wide band) i dont feel like changing the cats, the pos is rust welded, no one wants to touch it. But i still feel its got lots of life in it lol
Thanks patrons

No need for anything hi tech, I just used a "spacer" on a different car that had really high mileage and was going through the same thing, I wasn't about to drop thousands of dollars for new cat converters from a dealership over a light that came and went. The spacer worked great, the light never came back, and on a downstream O2 sensor, the only function that sensor is doing is saying whether or not the catalytic converter is pass or fail, it's not effecting engine performance.

I went on Ebay and got one, you can find ones also at local parts stores, they are sold as a "spark plug non-fouler". just make sure you do some measurement to be sure the one you get will fit, sometimes the length is an issue.
