Hello,
I am trying to help my brother diagnose a cylinder 2 misfire on his 2014 Ram 1500 3.6L. He has already replace the ignition coil on that cylinder with no improvement. I checked the number 2 injector with my PicoScope and it shows a good waveform except that it is about .365 ms shorter duration than the number 4 injector at idle. The misfire is on cylinder 2, cylinder 4 has no misfire. Is it normal to have a slight variation like that between injectors? I have attached an image of the two waveforms. The green trace is the good cylinder 4.
Thanks
