Way to revive your bad O2 sensors
Hi there
I recently had trouble with O2 sensors going bad. I had been running waaaay rich which was probably why they went bad. Anyway, I ordered some new ones. While I was waiting, I removed the old sensors and used brake kleen on them and blew them out well with a blow gun, they came back to life! I got my new O2s today and installed them since I had already bought them. It's just something you might want to try!

I did this on my other car- the 02s just get really dirty and if you clean them off they work fine again- my 02 sensor CE was coming on in that car and I saved on the damn 200 bucka pop 02s from the dealer

If you have to replace them go to http://www.buyoxygensensors.com .
They were $80 for BOTH SHIPPED - beats $100+ EACH. I got the generic ones that need a wiring job. I recommend doing it their way using the crimp connectors rather than soldering (which is what I did) the original wiring harness is extremely difficult to solder to.

I just changed both front O2 sensors a couple weeks ago. I have 95000 miles on my 97 and had been only getting a maximum of 260-270 per tank (usually 70/30 freeway/city). I had been getting such bad for the longest time...until I changed the O2 sensors! On the first full tank of gas afterwards, I immediately improved 3mpg 
But get this, I had also driven A LOT more city miles on this particular tank of gas.
The CEL for both front O2 sensors have come on several times in the past, with the last time being probably a year ago. Since the CEL didn't come on recently, I just ignored them, but I got sick of my bad gas mileage and changed them anyway. I guess this goes to show that even if the CEL doesn't come on, that doesn't mean the O2 sensors are still good. They can become lazy but not throw the CEL.

Re: Re: Way to revive your bad O2 sensors
I have an A/F ratio meter connected to one bank and a spare input from my S-AFC connected to the other bank that can read voltage. When you rev the engine to 2000 rpm (constant) under no-load conditions. You will see the voltage bounce up nd down 5 times in 10 seconds. For bad O2s, they just read zero volts until you rev the engine pretty hard. For the A/F gauge, you'll see the A/F bounce between lean and rich 5 times in 10 seconds.

I don't mean to sound like an a$$ but are you kidding me? If not then have someone do this for you. Or get a Haynes or Chilton manual. Do you know what a y-pipe is? If you do, they are on there (at least the ones I am talking about are there), if not then look in the manual

Can you tell me appoximately where they are located.
I would like to try this.

Thanks

Yes you do sound like an azz. This is a forum for infomation and the gathering of such. You should have known this person was a newb by the little words under their name "I finally posted something!" and directed such an inquiry to a search. Or you could have just as easily answered the ? without flaming. That's ok we all have bad days sometime. Remember you were new at one time.
