This is occurring while driving and while sitting at a red light , it's just all over the place. The only thing I can think of is the thermal temperature sensor has broken, but I'm hoping to get a confirmation from someone else who had the same thing happening
Ok . I dug this up . Here is a link to the page which has several follow up questions to ask. When you get to the site just close the popup asking you to sign in .

Engine temperature fluctuations in a 2007 Corvette can be caused by several factors, including issues with the cooling system, electronic sensors, airflow, or even head gasket problems.
Key causes include:
• Low coolant level or air in the cooling system: Insufficient coolant or trapped air prevents proper heat transfer, resulting in rapid temperature swings.
• Faulty thermostat: If the thermostat sticks open or closed, coolant flow is disrupted, leading to erratic temperature readings.
• Bad coolant temperature sensor: A malfunctioning sensor can send incorrect signals to the engine control unit (ECU), causing false or unstable readings on the gauge.
• Failing water pump: If the pump cannot circulate coolant efficiently, engine temperatures will fluctuate.
• Obstructions in radiator or condenser: Blockages can restrict airflow, especially at low speeds or idle, causing temperature spikes.
• Electric fan issues: Problems with fan operation or electrical circuits can impair proper cooling at low speeds.
• Blown head gasket or cracked head: In rare cases, combustion gases entering the cooling system can lead to rapid and unusual temperature changes, even without coolant loss or creamy oil.
