temp gauge reads 210...

But then it drops all the way to 260 when I hit a bump. Then I can smack it and then it goes back to 210 and then it falls off again... any ideas?

I had the same problem with all my gauges. I ended up cleaning up the ground on the firewall in the engine compartment. Gauges have worked perfectly ever since.
