2000 Temp gauge fluttering??? (6 Viewers)

I’m starting to notice my temperature gauge suddenly turning it off and back on like a flickering light. It started slowly. It’s starting to do it a little bit more. Coolant seems to be full and no leaks. Wondering if the temp sensor unit is going bad and if this is not an uncommon issue as these vehicle age.

Update: I decided to go ahead and replace the gauge sending unit and in the process a vacuum fitting broke off the air muffler box and the connector to the sending unit also broke. Some days repairs go better than other days with these old cars.
