    the speedo drive is on top of the passenger side differential drive shaft ,if this vehicle is a 92 then its a speed cable and this could be sticking and needs a good clean ,by removing the cable and then pulling the inner cable out and giving it a wipe with a oily rag then a good oiling and refitting

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.

1992 cadillac deville sedan speedometer was working off and on but not at all now--is this bad connection a simple fix or worse. Thanks tim

Well, if the speedometer needle is not working, this is a violation of PA State Inspection regulations. If the odometer is also not working, it could point to a bad wire or bad connection to the speed sensor.

Check connections as this is a common problem.

Does a 92' cadillac sedan deville top out at 85 mph like it says on the speedometer?

Unless your car has a governor installed on it (doubtful) your car will do more than 85mph. At various time the government in its infinite wisdom has set limits on what the speedometer can read as a way to discourage drivers sppeding and from seeing what their car can do as far as top speed. I mean what's the point of burying the speedometer and holding it when you can no longer tell how fast you are really going.
