N55 turns offf under 1000 rpm

Hi all,
My 135i 2011 N55 turns off under 1000 rpm and only when engine reaches normal function temp (not when its cool and not when accelerating). Only code found is poor mixing. What I have done until now:
- Found an air leakage (solved)
- Injectors: checked and cleaned
- spark plugs: changed
- MAF and MAP: checked
The problem still remains. Appreciate any suggestions.
Regards,
