Jumpy speedometer
 

I have a 2001 STS. About 103K on odometer.

Last weekend, while on my way to Boston in the rain, the speedometer started jumping, going from 80 to 0, back to 80, down to 0, then jumping at various speeds until finally going back to 80 or so, or whatever speed I was at. No problems thereafter, though on my way (not in the rain) it briefly jumped a bit.

So that's the problem.

Any ideas?
