1988 Pontiac Grand Prix, Ignition - Primary Waveform
Posted to the Waveform Library on 7/16/2001

This vehicle exhibited no symptoms. I was just going to capture some waveforms for a class study. It has a problem with one of the coil currents. Is this the product of a coil that's going bad or is it the module. I already know, what do you think? Why?
