Weirdest running rich problem above 3000rpm Hi all. Hope someone can help me with my problem. I have an R32 GTR, freshly build RB28. Mapped with Nistune. Car was running fine while we mapped it and also the day after that. Next day it had the weirdest problem. Car is running completly normal until exactly 3000rpm. Above 3000rpm the AFR drops to 10.5:1 instantly and stays there almost the entire rev range. Doesn't matter if I'm driving oder reving it in neutral. It also doesn't matter what settings we make in Nistune. It's always the same above 3000rpm. What we checked so far: -both AFM have rising voltage with rev and load -TPS has normal Voltage -has 3000km old Splitfire coilpacks -has 4000km old Mine's AFMs -has 200km old Sard 850cc high impedance injectors and resistor delete -tried a different CAS -shows normal water temperatur -shows normal IAT temperatur -problem also happens with unpluged O2-Sensors. Looks like some kind of limp mode to me, but can't figure it out. I'm realy pissed with the car (again). Hope someone can help me.

Hey people. I'm just wondering if anyone has any idea whatsoever what the issue may be with my V36. It recently started sputtering around 3200RPM as you can see in the video (Please ignore my dodgy display), nothing has been changed recently and I have tried resetting the ECU/throttle position/idle air/etc. I've checked for exhaust leaks and can't seem to see anything, the ecu is throwing a throttle position sensor code however advice from the interwebs mentioned to just reset the throttle position and nothing more. Happens in Auto and tiptronic regardless of gear, the only time it doesn't occur is when my foot is to the floor however that isn't feasible :P. Cheers in advance! Video of sputtering
