installing front O2's
Just received some replacement front O2's since the one on the pasenger went out, I will be replacing both the driver and passenger front 02. Any thing special I should know, or is it just replace and go. These are the "Denso first time fit" and it looks like they both came with a one foot long -4 wire-wiring harness and a tube of anti seeze.
-Thanks

Replacing stock ones with stock ones is a piece of cake. It may take 30 minutes if you try to do it with your feet.! 
After I did LT headers a while back the stock o2's werent cutting it for my setup so I had to put 02 Vette rear o2's in place of my fronts(the stock rears were removed with the cats) and that sucked bad. For whatever reason(probably just becuase I had to replace them
) the Vettes and trucks have different connectors so I had to do some splicing. Splicing isnt a big deal but for some reason the passenger side wiring had no slack to let out like the drivers side. So if you have to do this do your self a favor and get your truck in the air!

so if i change out my 02's with the vette 02's then these 2 codes will stop popping up...which year model 02's am i looking for....or a part number would be nice....

I just changed out the front O2s while my transfer case was out. Very easy . . . only tip I can think of is to use an automotive pick on the electrical connectors, where they clip to the body.
