rev guage up the shit? help!

[ke25sr]

the factory rev gauge on my KE25 has began playing up.

at first i figured its a old car its $&#$%. I put a spare on but same problem.
So i tried a after market sucker same problem.

Its not reading properly at all. It pulses from 0000 - 1500 most the time occasionally higher.

it seems to read ok under hard accleration.

Any 1 got any ideas?

thanks
