O2 sensor replacement
Replaced my front 2 O2 sensors today. It took me 3 hours. 2hrs 45min to do the passenger side, 15 min to do the driver side. The passenger side is every bit the bi*ch people say it is. Actually I do have 3 excuses for why it took so long on the passenger side.
1. I have a Lariat with the fender molding and had to remove that before I could remove the fender skirt.
2. I have rather large hands & forearms (definitely a hindrance)
3. I am 56 years old. This should be a breeze for you young whipper-snappers.
The O2 offset socket I bought was useless on the passenger side. I used a open end 7/8 wrench and it worked really well. It was just very tight and a lot of flipping the wrench around. When I unbolted the brace for the transmission fill tube, it didn't really move out of the way. It moves just a little bit, but every little bit helps. Unscrewing the sensor was tough because when I broke the sensor loose, it would spin freely which was hard with the pigtail flopping around. Putting the fender skirt back on is a lot easier than taking it off. Don't miss the clip studs that are attached to a connector on the engine side of the skirt. In my opinion, the skirt must be taken out of the way. I read where someone only unbolted it half way and folded it back. Must have been quite a move as I could not see how it could be done.
The reason for swapping them out was my continued quest to find a slight rough idle when stopped in gear with brake on.
It made no difference. The sensors I took out actually looked like you would want plug tips to look after being in service.
Oh well, at least I can cross this off the list.

Nice job. Did you happen to disconnect the battery while doing so?
Whats some info on the truck? Slight miss at idle could be a number of things.
Just read your other post regarding the miss. Sounds like you have a few things to look at. Might want to update that thread and see if any more responses come in
