Rough Idle

[fait_svx]

When I shift my svx to drive position, and sit there without moving, the rpm needle bounces. It seems like the car just wants to turn off. (I remember it did this a couple years ago,too. I forgot to fasten one of the clips on the airbox. )I checked my air filter, I put a k&n drop in about a year ago, and it looks clean. Anybody know why it would do this?
