Hi

Thanks for the pointers. I decided to have a look to see what was what, I
hadn't really looked to see where these sensors were. I think I've managed
to sort the problem now. I found a plug unclipped from what I think was the
O2 sensor, (top of intake after the air box, slightly above where I think
the MAF is?).

Please correct me if the above is not right, but since clipping the lead
back the car has run much better, no more hunting and the petrol smell from
the exhaust gas has now gone.

Thanks all.

Ian.

That's the MAF. The O2 sensor is on the exhaust.
