Is the tach in question the factory tach?

Your ignition module is failing...it's located on the front of the intake manifold...with a plug going into the top and bottom of it (about 2x4" grey rectangle).

There is a special socket that must be used to take out the screws (avail at any parts store). Also be sure to use the dielectric grease before remounting and be sure to mount it the correct way, I may be mistaken but I think both ends are the same size elec connections
