It seems to me that if the problem is only on very small throttle openings,
then the track of the TPS is probably the problem, unless the mapping is
poor.
It feels like she gets no fuell but onley air.

a whole one, for the the lambda probe readings to make sense to the computer

It doesn´t hesitate when i change the TPS setting but then the surging
starts.

yes.
