Default My Tach is a late sleeper?

Anyone had this problem before.In the early morning lately my tachometer lays at zero for about a half hour after I start to drive the car.When I rev the car up over 2k it will creep to 100RPM.Thats it though.
After that the tach suddenly wakes up.It works perfectly the rest of the time.It just seems to be in the morning.What could be the cause of this.Something is not catching.Does it have to do with moisture? any insights would be appreciated.

I believe there is a "tach-filter" on the back of your tachometer. This is usually the culprit..G/L
