My 1990 LCD speedometer has got me puzzled. All the digitals read fine when I turn the key on, but as soon as I start the engine, the LCD scrambles. It does this till I turn the key back off. I have had the cluster rebuilt and that didn't take care of the problem. Please help me, I am totally confused and about fed up.

I did a little research here on the forum. It turned out that the ground on the ignition coil was loose. I didn't have to, but I put a new coil on it and it works perfect! Now I know how fast I am going!
