Yes, Bad Thermostat. It is stuck OPEN or it is missing completely and not allowing the engine to maintain the needed temperature. This also will cause you to have poor mileage as the engine thinks it always needs more fuel.
Replace the Thermostat and save money and gain performance.

id get a new radiator cap with the same lb pressure on it and if that doesnt fix the problem a new thermostat you can change them yourself and only cost about $15 and $2 for a new gasket

Check the electrical connection of the gauge, looks like its loosing contact from time to time. Yea, you can drive it, but if gauge stop working alltogether you can overheat without even knowing it.
