First thing to check is the ground.

Where is the box grounded??...Also check to make sure your engine is grounded to the frame properly and securly.....also check all your connecters ti make sure you have them all crimped good and tight (stuff like an MSD box should really have all the connections soldered)..

you cold prolly check you dist cap too for cracks or anything goofy in there.

I believe the MSD needs to be grounded directly to the body, not the battery.

No it was doing before then. With msd disconnected it still does it but not nearly as bad.
