No probs mate, i realised where you must be when i saw your signature!
Unfortunately changing the lambda sensor hasnt helped and where before the readings in Datascan were just creaping up, now its just permanently reading 100 (which i believe is 1volt). I am going to check the 12v+ fheater wire rom the fusebox and the ground at the weekend to ensure that is ok..
anything else i could check?
Wierd thing is that i am still getting good mpg out of the her, she's done 278miles so far and still got just under 1/4 of a tank and no reserve light...
