Low Coolant? Weak Temerature sensor? Weak gauge Gauge working properly and recording the thermostat opening and closing as engine temperature fluctuates
what is the gaga manifold made of
When you turn a corner the guage fluctuates.
Manifold gauge/gauges are used to check both the high and low side pressures of the refrigerant inside the a/c system...................

Your pressure gauge may be broken....If it fluctuates, then you know its not your gauge, but if your gauge always reads 80, it may need to be replaced.
The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.
because your thermostat is opening and closing as the engine temp. fluctuates
Could be low on coolant or a faulty thermostat.
It goes to the temp gauge which is usually screwed in the head between the manifold on the drivers side, or into the thermost housing on the intake manifold.
Because it is a Pontiac. Sorry, man.
The gauge is part of the fuel pump/float assembly within the gas tank. It is probably a $500.00 repair. It is harmless.
