You replaced it? with a replacement or you took out the original and put the original back in.

Did you do anything under the hood...specifically with the tach wire on the distributor?

Did you reconnect everything behind the dash the way it came off?

I had the same problem when I replaced my cluster on my 84. It was the tach filter (out of the distributor) that was bad. Found it at Eckler's or MidAmerica, don't recall which, for about $30.00. Dave
