lambda system freeking out in a 930

hi fellows Pelicans.
lambda system is freaking out in my 86 930. it is a US version - 930/68, with lambda circuit controlling mixture/emission.

car runs great without lambda sensor connected. once it is hooked up, however, AFR goes down to ~10 or even below.

once sensor is disconnected, it goes back to whatever is set using mixture screw.
below two videos showing how it behaves.

lambda sensor has already been replaced with new unit.

anyone any ideas?
