Lately the speedometer needle has not been steady. It has been wiggling around the speed the car is at and the when you hit a bump the needle will hit 0 mph and bounce back to where it was at. Would this be a problem with a fuse or sensor? Or just some simple little part that needs to be replaced?

Sounds like a loose wire to me.

Check the speed sensor on the tranny and the wires on the back of the cluster. Id put my money on the speed sensor though.

If is indeed a bad speed sensor how much does that piece run?

Like $30. But its probably just a wire.

Actually to me it sound like the little motor that runs your speedo needle is taking a crap on itself. Mine was like that for a while. I took it out adjusted it (the little magnetic tips) and it was fine for a while then it got bad again and i took it out and so on untill now i just ignore it and I know how fast I am going by rpm and gear. Till I get around to going to a junk yard and getting that little motor to replace mine.

I always had a problem with the speedo gear getting stripped, but it was the crappy...23 tooth I believe?
