Its 23142 and 23139 for the up and down streams. My brother inlaw mentioned using a product called cataclean for the catalytic converter. Apparently it cost about 20$ and its cleans it out...? Are you using a obd reader? Wish i could offer more help :/

I haven't heard of that before. I will have to try it and see. Cat could use a good cleaning, I'm sure.
I have not used a reader to get that code. The reader only told me of the faulty O2S. I am getting that from the diagnostic trick of turning the ignition on and off three times and having it give me the readout on the odometer. By replacing my power steering switch, the O2 sensor, and a couple other things, I have cleared all codes (I had like five or six...thanks PO) except that pesky 42. Hoping its not the fuel pump, but that is kinda the direction I am sort of reluctantly looking.

Because its sold at Canadian Tire, you might not have access to it but there are similar products:
Catalytic Converter Cleaner (16 oz.) : Amazon.com : Automotive

This just an example but i would talk to your local shops first as thos might be snake oil... Btw code 42 i think means something to do with the catalytic converter.

:/

My other o2 are on the way but delayed because of that huge snow storm (funny im just on the edge of it). Got gouged on the price because shipping is different from California and Ohio. Last time i ordered i payed 12$ from ohio for shipping. This time 42$ from California. What a jip.

Well, I have had the new sensor installed for about two months, and I have run a couple full tanks through it, and I am now averaging between 13-15 mpg, which is much better than the 8-10 I was getting before the O2 sensor.

Huge thanks to all who gave their input, and to Jerry for recommending the NTK sensors through Rock Auto. They were almost half the cost of the Bosch ones at AutoZone, and I liked the idea of keeping it OEM. (BTW, the faulty sensor that I took off and the PO replaced just last summer was in fact a Bosch sensor. Will not be buying Bosch in the future).

I will keep subscribed to this thread to offer any help to anyone else, and giving any necessary updates. Thanks for all the help. WF has been the best place for all the help I need.

Evidently, the oxygen sensor inputs are a lot more critical than some folks claim.
