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.
