Next time it happens, slap the dashbaord and see what happens. What is really weird is the spedo using 20 as a zero.
The way the spedo and tach work (or used to) is that they read pulses. The faster the pulse the higher the spedo reads. That is a hard stop at 20mph. Whatever the problem is is in the gauge cluster, 1999 had a gauge issue but I havent heard of any 2000's having one. There are four large plugs and one small one for the spedo itself. SO I am ruling out anything originaiting from outside the cluster.
Lets start with taking the cluster out, taking it apart (its as complicated as playing with a set of leggos) and cleaning all the contacts and anywhere there is a screw terminal on anything electrical.
After that it may be a short in the cluster itself. Just my educated guesses.
Is it worse in hot weather or cold? Is it worse with the lights on or off?
