yo ZALE!

I also replied to your similar post in the General Section

Is it the one on driver's side? Do you have just one O2 sensor in it?

Call your local NAPA;

Tell em which O2 sensor and connector you need; or go there with the connector & sensor.

Such as

Oxygen (O2) Sensor

Product Line: Bosch BSH 15729 :

61.49 Each

or

BSH 15716 48.99

Each

Oxygen Sensor Connector

Product Line: Echlin Ignition

ECH EC98 Price 16.99 Each

Color Code: Black;w/ 4 Wires

Identification & Location; "...Regardless of how the engine is mounted in the vehicle, conventional or transverse, the HO2S naming convention stays the same in relationship to engine banks 1 and 2. Bank 1 will always be the bank containing the #1 cylinder. See Fig. 1 in TSB 01-9-7..."

this is for a 96 but the "BANK" # is std for most years

Also; did this cause it to burn?

Well the 02 sensor does partner up with the exhaust that gets really hot...

It's easy to tell if you need upstream or downstream - Look for the 02 sensor on the exhaust pipe. The O2 closest to the muffler (back of the car) is downstream. The 02 closest to the motor is upstream.

Easy to change..altho, I had to use a wrench in order to remove mine..with a 3ft breaker bar lol. You could try an 02 socket but my experince is that it just rounds the edges. Wrench will have very little space to work with, but is possible.

As Adam wrote the pass side is located on the exh pipe;

I had to use a lot of PB Blaster and a torch on it last fall...
