Replaced O2, and went oops

[BamSHO]

Well finally got the money and time to replace the upstream O2 sensors. What a pain in the butt, thought the atx Gen2 I had was bad. Well I guess its not a good thing when the O2 plugs still matches the wiring harness plug (color) and both have FORD part numbers on them. Not saying they werent changed, but it sure doesnt look like it. Now just have to do the other ones, ugh Im not looking foward to that.

Why are you changing the rear ones? They don't do anything performance wise.
