My exhaust flanges separated from the pipe so I just went out and got 2 of them from the junkyard... I'm going to run straight pipe from those to my muffler, because the cats rattle, and i cannot afford new ones, and the only thing keeping me from doing this is my 2 o2 sensors (1995 3.9L engine, so I don't have o2 sensors after the cats)

I've read that you can purchase dummy o2 sensors that feed the ECU info so it thinks everything is fine, does anyone know were i can get these? Or what type of circuit is inside the o2 sensor so i can replicate it?

Thanks

 

Cany you just use your old ones?
Even if you get dummy ones they still need to be installed.
I do not know where you can get dummy ones.
You could get universal ones for have way cheap. Probally cheaper than the dummy's.

 

the holes for o2 sensors will be gone... there is not enough pipe between the hole and and the cat to save them

 

You will have to drill new O2 holes and tap threads or weld them in.

 

yeah... thats why i was hoping for dummy o2 sensors...

 

You mean like this??

Ithink that dummy o2's need to be installed too, they need to get hot to work, I might be wrong...but a muffler shop can install your o2's for cheap.

 

bingo!

thanks... I really appreciate it

 

Those are not the kind I have seen.
The ones I have seen look just like a O2.

 

I am assuming that you live in an area where they do not do emission testing. I personally think dummy O2 sensors is a good way to cause real problems with your engine.
