    For you who have done this, is it worth spending the $100? I have a 420 code being thrown on my truck and I'm wondering if this will help solve it as well as the recent drop in mpg. They only offer a downstream one, and i was under the impression that it was the upstream one that did the fuel to oxygen ratio adjustments? Thoughts???

    I have done this it does work it is for the down stream sensor. its a tedious task and kind of scary cutting into wiring harness but it is not to bad. i soldered mine and electrical taped the harness to the dash frame to support it from disconnecting somehow. i got it because i removed my cats inards. ive heard you can just get a relay. and thats all it is . im not sure if thats what it is called exactly it just mimics what the computer wants to see to prevent light from comming on and allow it to run on just one sensor. its what is behind the cat that matters is why they dont just delete the rear sensor. it measures the resistance between the front and rear sensor. if your cat was gone it wouldnt read right and light would come on and it would tell the computer that there is too much gas because the catalyst is gone to burn it and the truck would run very lean. the simulator allows it to think the truck is running correctly. only do this if you do not have to worry about state emmissions testing.

    I would try spark plug non-foulers. They come in backs of 2 and can be had at any auto parts store. Buy 2 packs drill 2 of them out then stack them put your o2 sensor in the drilled out one, screw back into to your exhaust and it should solve your problem.
