Car going crazy...

Hey ive got a 2.8L 88' Camaro.
Lately when im going down the road all of a sudden the RPMs just start going nuts.
What I mean by this is, say im going like 45, my RPMs are at like 20. And all of a sudden it just started jumping up and down between 25-30.
Its extremely annoying and I cant figure it out...Any suggestions?
