Lambda probes problem Micra K11

Moin! I have a real problem here with the mixture preparation of my K11! I was at ATU this summer because my diagnostic lamp was working on. After reading out I got a horny computer print out that costs 20€! The computer print described the error from a defective cable to the capital engine damage!! (ATU stop!) The installer then said it will be very likely the LMM! This I had then changed and the lamp stayed out! Also the use of 10L went to 6 L back in the city! As a precaution also the temperature sensor was changed! Now went on again like warning lamp and I drove to Nissan! To the ATU Oracle I had no more pock! The diagnosis fell on Lambda probe it would still regulates work but too lean! Therefore comes from time to time to the error message Bank1 too lean! Was also plausible because error message only came up after a longer distance drive! I then ordered a new probe from NGK and installed yesterday! Battery w 10 minutes stuck and after the exchange 15km test driven! No jerked and no warning lamp! This morning he jumps well as always only I can not get over 40KMH! No performance! Does anyone still have an idea?? Is a K11 CG10DE of 01! Mfg
