Hi,

I got this code and is wondering what should I do.

It is a 96 Contour with 2.5L V6 engine at 100K. I have took it in to a local mechanic which asked for 900(parts and labour where the part is 600 which I assume is the pre-cat).

I also tried local Ford dealer which quote me a much cheaper price of 300 or so which I believe is the main cat rather than the pre-cat(as they said they don't know what is bank 1 and there is only one catalytic converter in the car).

Reading the post here, it seems that I can also just try the Berryman's B12 clean up first(I think I would go this route first) and may be the mileliminator.

If I don't change the pre-cat/cat(which one should be the right one to change), what would be the effect to the car, other than that it may fail emission test ?

thanks for any help in advance.




one thing do not just change your O2 sensor, if you have either P0420 or P0430 best is go a head change catalytic converter. cause I have both code show at 148000 miles, and i didn't clean then i had both catalytic converter change new and also change the O2 sensor the same time, so it will be fresh and clean. even thought that if you clean the cat, after few miles the same code it will show again with out any question to ask. I am not sure how much it will cost for just clean, but the money you use for clean you can add little bit more to have mechanic to put a new one on and it will last you for another 100,000 or more miles. what the P0420 and P0430 is really are Intake Manifold Catalytic Converter *IMCC*. it was a intake manifold with Catalytic converter underneth. always remember on the Duratech V6 has 3 Catalytic converter. when I got my change in the dealer, it was like $750 each include labor, parts and tax. if you just clean it and reset the computer, either way it will still show after few miles later. trust me, i did all those untill now i change both Intake Manifold Catalytic Converter.
