I bought mine from the dealer for about $120 and it took less then 10 minutes to install. Hope this helps.

I realize I probably know the answer to this question already, but I have to ask. Can we use an aftermarket O2 sensor? $120 is a little steep right now.

That is interesting. Thanks for the input. I think I can get a universal O2 sensor for about $56 from Pep Boys. I like that price much better than $120....

I don't pretend to know why, but there are a couple of threads around talking about how you shoudl NOT run Bosch sensors.

Gadget's company URD is selling Denso OEM parts for a pretty good price:

http://www.urdusa.com/Merchant2/merc...tegory_Code=O2

1997 All L4-2.7 2WD
Front = 234-4162, $82.99
Rear = 234-4153, $77.99

Dunno.. Drop 'em a line dood! (info@urdusa.com) I'd 1/2 way expect that one of those units should work.

Sorry...haven't been on in a bit, but I just got a new and put it on. It seems to be working great. Try www.sparkplugs.com...they've got a denso universal that runs 49.95. All you've got to do is cut the plug off the old one...they've got the instructions and connections in the box with the new sensor.

What "plug" exactly are you cutting off? I think my 02 sensor is dead..since I am in California I think I have 2 sensors as well. Are they both fried or just 1?

After you change it do you have to reset the computer or does it automatically reset itself? Thanks

You have to reset it. After I changed mine out last week I just took it to Autozone and they reset it.
