Thank you Mike.
I took my sensor out this morning. It was smoky in colour but not very dirty. Following Peter's tip I bought two spacers from `janspeed. For the moment I have fitted the spacer to the nearside Cat. My sensor is connected to the front of the Cat. I will need to check to ascertain whether I should do the same to the offside Cat. It is too soon to know whether the MIL light will remain off and as the code indicates a weak signal to the oxygen sensor I need to discover the cause. If anyone has any suggestions I would be pleased to here them.
