Not sure what the problem is...but it's not normal because mine just started bouncing a couple of years ago.

Welcome to the world of General Motors! lol This seems to be a common thing amongst alot of GM's, all of them I've ever had have done it also, (except my LS because it's an original FI car), I guess I've always assumed its a bad sender or maybe a bad ground? Let us know what you figure out.
