This can be a sign of a bad compressor and you will need to run a compressor check first, this can be done without draining the freon....
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
Manifold gauge/gauges are used to check both the high and low side pressures of the refrigerant inside the a/c system...................

When you turn a corner the guage fluctuates.
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.
No, you should not use an R22 manifold gauge set for R410A. R410A operates at higher pressures than R22, and using an R22 gauge set could lead to inaccurate readings and potential equipment damage. It's essential to use a manifold gauge set specifically designed for R410A to ensure safety and proper functionality.
Because it is a Pontiac. Sorry, man.
