BMW Z3 rough idle on start codes read P1189 , P0304(cyl 4 misfire) ,P0306(cyl 6 misfire), P0305(cyl 5 misfire) ,P0173....cleared the codes and the idle immediately went to normal.
All the codes you have are all related to the fuel trim, this problem needs to be looked at with a european capable scanner for futher tests sorry.
