2005 International 4400, ECM/Inputs/Outputs Waveform
Posted to the Waveform Library on 2/22/2014

This capture is at 1200 RPM when the engine starts to misfire badly. The green trace is #1 injector current. You see the other injectors through inductive interference as the smaller peaks. The ECM is cutting out the injectors to limit RPM.
