it has a short somewhere in the electrical line
Bad sending unit in tank.
The cluster is another name for the gauge assembly.
I have found though my experiences that 99% of the time the fuel gauge sending unit in the tank has failed.
If you have 10 lbs of oil pressure per 1000 rpms, your fine.
You have a ground from the oil sender unit to the gauge. This is how you check a gauge. ground out the wire at the sender and it pegs out the gauge.

It goes up while driving and down when you're idle....that's normal

It depends on the setpoint of the thermostat.
180-200 F
The heater blowing cold air and a fluctuating temperature gauge in a 2005 Pontiac Grand Prix could indicate a few issues. One common cause is low coolant levels, potentially due to a leak, which can prevent proper circulation and heating. Another possibility is a malfunctioning thermostat that may be stuck open, preventing the engine from reaching the optimal operating temperature. Additionally, air trapped in the cooling system can also lead to inconsistent heating and gauge fluctuations.
If the temperature gauge is not working, one thing it could be besides the gauge itself is a blown fuse. Another possibility is a loose or broken wire on the gauge.Ê

Anywhere as long as it is not in either extreme position, Remember gauges are just an indicator and not "gospel"

Remove oil pressure sensor and install a manual gauge
