oxygen sensors
I am going to replace my o2 sensors F+R. I found the front easy
enought and i know the rear is before the catalytic converter but is the rear accessible with just lifting the car? or is it underneath something? My haynes book does not show a picture or describe its exact location. |

I replaced my 02 sensor on my '94SL1 last year due to some gas milage problems. My suggestion if you do have problems in the future is to get one out of a car at the wreckers. Save's big bucks if you are having problems and are not totally sure what the problem is. Local shop wanted ~$200 for a new o2. Got mine for $10. Turns out the o2 wasn't the problem anyways. |

I went to autozone and they said the F+R were reading slow. Is the
downstream as accessible as the upstream? I have an inspection and i don't want to the service engine light to be on. So i am going to replace them and hopefully the light goes out.
