[jgianettino]

hey guys, Going to replace all four OX sensors this week end, any tips? 156K on the car, had a code come up past weekend, one sensor bad.. alough I know it might not be the sensor, but Ford says 100K replace them all... If anyone did this before please reply, any tricks? I looked and it looks pretty easy--- ?

It's pretty straight forward. are you getting generic or OE?

Do yourself a favor and get a socket designed for the job. Autozone & Advance Auto "loans" them while Sears and Napa sells them.

I think they are OE, I got them from Rock auto, But I am confused, my code read P156 bank 1 sensor 2 behind the cat, but when I went under there there are 4 two each side one in front of this bulb like thing on the exhaust, My cat is way down stream from there, or do I have two cats one on each side?
