Lupo 1.4 Engine management light

[Trout13]

I know this has been done to death but I still cannot get to the bottom of the cause. I have fitted a new throttle body which kept it off for a few days. My pals generic vagcom still says bank 1 running lean and the Longft sits at -65% when idling, Im not sure if this is correct or not but doesnt seem right to me. I have sprayed for around the manifold etc looking for leaks but nothing.



Anyone any ideas?
