Tach Waay off(91 V6)

Uh Yea the tach has recently started being inaccurate as of last fall.. i dont understand it, why does it read higher then normal? Theres no way in hell im tachin 3 grand at 80 somethin mph.. it was taching 3 grand at 90mph when it was working normal.
~+~+~+~+This is so annoying to the point of frustration, not knowing what im tachin at and altho i never go WOT i do have to pass ppl occassionally.

>>>>>>>>>>>>Is there anything i can do about it that wont cost me a arm and leg, im in school and i am struggling as it is so any cheap fixes that dont require me to have a ASE certification would be great..
thanx
