You may have several issues. The best place to start is to have the trouble codes pulled. Any Advance Atuo or Auto Zone will do this for free. As far as the speedometer goes you may have a bad speed snesor or the speedometer itself could be bad. Usually the speed sensor will fail first.

Check the coffin box, located right side engine near passenger. It has a hard plastic cover and attached by 4 lug screws. Once you open, you will see several computer modules. The one at the far back should have fuses inserted into it. They should all be 10amp. Check them all and I will bet that one is bad. It controls your speed censor and ABS. It has worked for numerous people. Thanks
