Miss nightmare

Post by RS-4 » Mon Oct 28, 2019 10:32 pm

Hi folks, please help with this waveform. Car is BMW E91 with N43B16 engine and MSD 81.2 ecu. Problem is missfire but missfire without fail code and with very little counter on OBD missfire on all cilinders. Coil, spark plugs and injectors are brend new, mechanical part of the engine (cilindar pressure, vacum leak etc...) is ok ... For me waveform say lean condition ... maby I'm wrong.

Thanks in advanced.
