Just a quick warning about renewing the good old O2 sensors. Did mine three weeks ago and all was well, more MPG etc.

But today the RR is running like it was before :evil:

Got under the bonet to find the wire from the left hand sensor was in half, found it had been rubbing against the drive shaft.

Good old gravity had done it's thing. So thats what a cable tie is for, is it..............?

what prompted the sensor change?

I had very poor MPG and other isues with ny RR. Bought a box of tricks from Blackbox Solutions, that told me that one of the O2 sensors was in open loop, ie not working at all and the other on had poor out put, 0-3v when it needed to be 0-5v.
