1987 Ford F-150 Custom, Ignition - Secondary Waveform
Posted to the Waveform Library on 4/15/2005

Bad hall (pip) signal causing this condition. I read other posts that talked about a #2 cyl misfire in particular. You can clearly see that here. Other cyls are affected too but #2 was definately the worst.
