was about £70 IIRC and came pretty quick, its what im running now and mine was setup against stus calibrated wideband and using this probe we were spot on

cheers for that dave, after diagnosing it i went to call stu, but the phone was engaged.
so i had a quick look around on ebay and found them for sale from graham goode, genuine ford sapphire 4x4 lambda for £47 quid delivered
get some bargains on ebay some times
will fit it over the weekend and let you know if it works.
