how in the world?? 95 oxygen sensor.

[genner21]

I have a oxygen sensor code. 1221. I check under the car for the sensor and this sensor is in a very tight spot. If any body else has done this it would help if you knew what wrench size and how i can make this work. Remember its a obd1, only have one sensor. I also have a Automatic, so its by the transmision. anybody know how in the world i'm gonna do this? any help would be aprreciated. :help

At least you dont have obd2 and need to change the pre cat ones out....those are a biotch. Its either a 22mm or a 24mm wrench (I forget). Put your car up on jackstands, crawl under there and find the point on your exhaust where there is only a single pipe, and I believe the sensor will be there. Have fun.... ;)
