I finally got my o2 sensors replaced on my 94' with the 2 upstream sensors. My check light came on after an unexpecting meeting of a ditch in the middle of AZ in pouring snow. I was lucky enough not to hit anything, but it did blow out my o2 sensors.
I found the Walker units on Amazon for $53 a piece, part # 250-24501 Same for both sides. Very nice units, but only one came with a new gasket, so I cut one out using the one I did have as a template using exhaust manifold gasket sheet. Easy fix.
If you don't have stock running boards, replacing the units is very easy. If you still have them on, well, good luck getting to them. They look like stock, plug in like stock, and install just like the stock ones do, for what, 1/3 price. Now they perform like stock? YES
I did reset my ECM after the install and it took a good 50 miles for the truck to get up speed with idle and such. I have had them on for about 400 miles with no check lights and my idle has really smoothed out. It was running around 450 rpm idle, shakey and rough as *&^$. Now i have a nice 600 or so rpm, no shake and no rough spots. Although I think it needs a basic tune up now that I have done a good inspection of all the bits and pieces in the engine bay.
The only thing I wonder now is how long they will last. Hope this helps with some folks that have put off doing the o2 sensors because of the $ of OEM's.
