RPM fluttering

My Tach is fluttering and I cannot figure out what would cause this? I replaced the pickup coil and the module and I keep the plugs, wires and distributor with rotor replaced every 6 months. I use top of the ;line products and I still have not figured out what is causing my Tach to flutter. Would the flittering problem also cause stalling?
Thanks for any help

I found that problem thanks to all who helped. It was my coil. Even though it looked good I was replacing the fuel pressure regulator when I bumped the coil and it wiggled. I replaced it with a new one. Tach no longer flutters. Whenever I hit bumps the coil would move causing the tach to jump.

Because the negative coil is wired directly to the tach, is why you experienced the fluctuation. By the way, sometimes a defective tach can short out an ignition coil.
