My car has always had a little bit of a miss when it's first started and drove when cold at around 2-2500 rpms, this miss goes away after the engine has warmed up.

Every time I drive the car and run it under a hard pull the tach always flutters like it is misfiring between 3500 to 5000 rpms, I can't really notice a miss in the car but there is definitelty something going on, both my stock tach and the autometer tach both flutter. Anyone ever experienced this?? I have a fresh rebuilt dizzy with all new OEM parts, new cap and rotor button, also have new plugs and wires. My ignition is accel 300+. I had this problem before adding the ignition and rebuilding the dizzy.
