Jiggly Temp gauge

[positron1]

Searched and came up with maybe a bad thermo. Yesterday I noticed that while driving, my temp gauge needle goes to C and starts to jiggle back and forth yet when I come to a stand still, it's reads normal. Has anyone had this problem, what's going on and how do I fix it? Any other suggestions?

Check the actual connection at the temp sender on the intake manifold.

Thanks! I'm on it!

The clip at the end of the wire going to the temp sensor was loose, very loose and bent slightly so I got a set of needle nose pliers and bent it back to it's original position and snapped it back on tightly. Problem fixed! Thanks!
