For whatever reason, my speedometer, fuel gage, temp gage, and possibly the oil pressure gage just quick working properly. The needle for the speedo has turned the whole way past 140, the fuel gage needle reads full all the time and bounces a little, and the temp gage stays at cold. Anyone know what the heck is goin on here??

 

It's possible that the whole gauge cluster is shot and would need to be replaced.

If it was just one gauge, I would say the stepper motor in that one is bad, but for all of them to do that... I would think you got a bad cluster

 

I know very little about wiring, so others can jump in with more expertise, but could that be a loose wire/bad contact - either power or ground? I'm thinking that if you lost power or ground to your gauges, they would all behave as you describe.
