1991 deville speedometer jumps from 0 to 40 sporadically and fuel data center bounces between option (avg., miles to empty,fuel used) even though the fuel level shows correctly. change oil light comes on...

Well I was going to say it sounds like a faulty transmission speed sensor, but the headlight circuit would not affect that.
Could be a short somewhere in the harness for the instrument cluster.

I was hooking a new stereo up in my 1991 Cadillac sedan deville and sparked a wire and now its running rough. what could it have did?

What you did was sent 12Volt Power through the Entire car. There is no way for ANYONE to know what damage you have caused. The Computer could be fried, Sensors, the list goes on and on as you can tell about putting the Old Stereo in and it working..

This is the same as Jumping your car and putting the wires on backwards... Only Worse, you bypassed the Security Features of the Fuses....

Sorry but you are going to have to troubleshoot every system to find out what damage has been done

How to fix code e98 1991 deville

Probably two different issues.

The code is saying the computer sees the engine RPM is too high when shifting between park neutral and drive.
The rough idle would be something else.
