This may sound like a stupid ? But I am legally blind...
I just got the truck and When I bought it the exhaust was missing from the cat back So I am checking things. Now if the PO removed it or something stupid like that I need to be sure I didn't just miss it when I was checking for it. It isn't on the Y pipe, so where is the damn thing! LOL
If it's bank-fired, it really shouldn't matter whether it's one O2S or two. The two cylinder banks should average out the same, which is the reason that Ford stuck with a single HO2S up until sequential fuel injection.
I can get some pics up tomorrow if you all want. I just gutted the interior, I am going to do the intire floor and bed area with Herculiner. The paint is shot. I will be doing the bottom 1/4 of the body with black Herculiner and the top will be Black too. The rest of the body will be red. and the fenders are just cut out. I am running 38"x15" TSL's with no lift. I have to tub the rear to clear the 38's.
I am blind and no one wants to go out in the dark and look. The pics were for those who want to see the Bronco. I am at the mercy of others when it comes to some things. Wire color and pics are two of them.
