Apart from dodgy idling etc are these worth changing due to old age? I think im running the originals and one is smashed to pieces but as its the one after the cat from what im read this does very little anyway.
I was thinking of buying a replacement sensor for the pre cat hole and moving the current pre cat to post cat to replace the broken one, is this pointless or worth £50?
