Replacing O2 Sensor
Is there anyone who can give me step by step instructions for changing my O2 sensor. I am not very mechanical, but I try to do anything I possibly can myself. If it is too complicated I will have to take it to a garage, but I would rather save money if I can.
Thanks!
Thanks!

locate the o2 sensor on the rear exhaust manifold.
if you are trying to save the old sensor, rent this kit from your local parts store
if you don't care about the sensor, just cut the wire off and use a deepwell socket to remove it.
it will be easiest to remove if you have the exhaust pipe warmed up, but not so hot you can't touch it.
if it doesn't want to break loose, spray some penetrating oil on it.
installing the new sensor is just backwards.
apply some anti-seize on the threads before installing it (should be included) and tighten with the special socket or open-end wrench.

Here is a pic of the O2 on my 93. Your'* will be in the same location. This pic is of the rear exhaust manifold and down pipe by the firewall.

thank you, the picture helps alot. I am hoping that I can find someone to help me do it. I would hate to pay a mechanic again. I think i've put about $2100.00 in this car in the past 6 months!
