On my 86 camry, as soon as it gets to a higher rev my brake and charge warning lights come on and the temp gauge starts to climb but as soon as i let of the gas and the revs come back down everthing is fine.
What is going on with my car????

Check the alternator belt for proper tightness. If that is fine, then check the alternator and battery with a DVM. It should be around 12-1/4 volts with the engine off and around 14 to 14-1/4 volts with the engine running. You will probably find that the alternator is barely over 12 volts with the engine running. It's time for a new alternator.

"temp gauge starts to climb" = thermostat maybe?

This happened to me on my 87 Camry and it was the thermostat. :2cents:
