hi

sounds similar to what mine does. There is a screw behind the tacho that has a split washer that became loose on mine and caused it to do the same thing.

tightening up the screw should fix the problem, maybe a dash of loctite or a new split washer could help also.

pulled dash a part today and cluster out all screws are tight and no loose wires or dirty connections.. i think a trip to the auto electrician is the only fix now. and also it is worse over bumpy roads....?

I have the same problem now, I think my suspension is too hard and has jolted something loose. Will pull speedo cluster out and have a nosey around.

Yup my old cluster would do exactly the same thing between like 3000 and 4500 rpm it would go ape shite. It is the tacho it's self coz i just chucked in a new cluster and it hasn't failed once. My old cluster has since been tested in another car and it played up. One day when i'm bored i'll actaully attack the old cluster and see if I can get a definite answer on whats wrong. If I can fix it I might even sell it instead of having a museum of old skyline parts
