1991 Oldsmobile Cutlass Ciera, Ignition - Primary Waveform
Posted to the Waveform Library on 2/7/2003

The pattern on the left is primary current before replacing the module. On the right is with the new module. I thought fo rsure it was a bad coil, but after replacing the coil the pattern did not change.
