Anyone have problems with ford racing 9mm wires? Just had an electronic stethescope under the hood and there was a ton of interference coming out of the wires. The stethoscope could pull interference 3 feet away from the dizzy. I have an msd coil but I don't think it bumps the signal enough to create this issue. They sound like they should be jumping between eachother but you can't see it. It's odd.
