Answer
You either have a fault in the speedometer cluster and or in the computer. You need to perform some simple electrical tests to determine which is at fault.

You will need, If necessary, Electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
