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

coil primary current (bad hall effect causing condition) the reason i'm saying it is the #2 cyl that is not firing is because #2 cyl shows the misfire in the secondary pattern. i cannot dual trace this scope when using the low amp probe
