Oil Pressure gauge flucuates from over 40 to close to red zone when idling on 1996 Pontiac Bonneville

When the engine first starts up the gauge reads over 40, it will drop slightly when you start to drive. When you have to stop at traffic light the gauge slowly drops toward red zone and pressure rises again when you accelerate.
