Wow. Great info. Yes the MSD Box is 12 years old, in the engine compartment, be it on the bottom of the passenger side away from the headers.
I was first going to try an E core coil to see if that works. Its approx $40 so it may be a cheap attempt to solve the problem.
If that doesn't work, I will most likely change out the ignition box. But if not MSD, what's your suggest? Will it plug into the MSD distributor?
You don't think it has anything to do with a voltage drop when the radiator fan kicks on?
Thanks.
