Speedometer Gauge Jumps Back And Forth.

The speedometer gauge in my 1979 280zx jumps back and forth from 0 to 110mph while driving and sometimes sitting still. The oil pressure gauge also turns on and off every 15 seconds are so. And every once in a while the rpm gauge will stick. Would new cables fix these problems or is it something more serious? The car has been sitting for about 10 years and I have just recenly got it runnng and I am just trying to fix all the little junk with it now. Any comments or suggestions would be greatly appreciated! Thanks!

Greasing the cables will likely stop the needle jumping. Cleaning the oil sending unit connection may help.
