Sometimes if your Mass air meter is bad then it will surge like that. It will either idle really high or barely run when your meter is bad

You could also try and clean your MAF.

It needs to be plugged into a tech II and the codes read..if it is running like that there will be codes to be read...that will tell you what you want to know..better to work from a position of knowedge than to just start throwing parts at it..

Scan it. In addition to the possibles above, It could also be MAP sensor going bad or the rubber seal on the MAP sensor has dried out. MAP sensor is in the back of the intake.

It can be almost any sensor. It can be the fuel pump voltage. It can be a bad tune. It can be bad injectors. We can go on all day. I say get it scanned and if you can't do that start w/ the obvious and process of elimination.
