Secondary waveforms.Honda fit/jazz 2003 1.4 was created by ian.evesham
hi
very new to secondary waveform analysis,so here goes.
Honda fit 1.4 dsi,captures taken from the front coils using a cop probe.
Engine is showing misfires,but not many.The car runs very poor mostly,lacking power.
Can anybody cast their eye over the pico captures.Turbulence on the burn lines of 2 and 3 stand out.no1 looks pretty good. No fault codes

The .psdata files can be opened with Picoscope 6. I have inverted the waveforms, and captured a screenshot of one event, per file.
