Well this is still bugging me. It does seem to spike lean a little when the power drops. Ignition wise, would I notice? It seems to pull clean, but the chart reads otherwise. In checking the coils resistance, will that give me a good idea on its output by any chance?
Hmm it is a MSD coil, also has a MSD 6a. Anyone know if a autoparts store can check a coil's output? I know Napa can check the ICM, but can they also check the coil?
