In addition to what Harold mentioned, another cause of this condition could be an electrical ground problem. A method to test this would be to see if the flickering changes with voltage load. In other words is there increased flickering as more electrical items are turned on. If this is the case than you should check all of the system main grounds. Start with the front frame extension ground located at the LH horn bracket, if that doesn't correct the problem check the main frame ground at the RH trailing arm bushing bracket, the auxiliary frame ground at the RR frame member, and the engine block ground at the RH motor mount. There are several other ground connections that may cause your tach flickering but the ones I named are the most common.

Have you checked fuse 1 for good contact? Also, be sure the ground wire to the ECU is in place and making proper connection. When is the last time you did a tune-up? A faulty or used up Dist cap and/or rotor could be at fault. Plug wires?
