found the problem an its sorted ,,just after i fitted the new lamda ,,it still lost power so i pulled at every wire i could see then ,a wire came free two brown wires conected to two bolts above the cam belt so morale of the story save yer self 150 pound and check all wires first,,,doh numpty,,,could have had a right good piss up on that money ,,,still its had one major overhall,,,lol
