1999 Ford Explorer, Ignition - Secondary Waveform
Posted to the Waveform Library on 3/21/2002

Top waveform is of #3 cyl firing on power, bottom waveform is #2 cyl capacitive pickup of scope picking up and displaying RF which makes it look like #2 cyl is firing at the same time. #2 cyl is not actually firing, although it sure appears as though it is.
