What can I do about a bouncing tach? When I shift, the needle wildly bounces around until the rpm settles in a gear. Then it either climbs or drops depending on acceleration or decelaration. Any ideas? (IMG:style_emoticons/default/confused24.gif)

If your car still has ignition points, check them or replace them and the condensor.
If not, then rebuilding your tach will likely be needed. --DD |
