Those are the classic symptoms of a bad MAF.

Seems like alot of people are experiencing bad MAF sensors. Try to put in a known good one before throwing more parts in. That is the cheapest and easiest way to diagnose it.

If its a bad MAF u might wanna consider going to a newer style LT1 MAF sensor with a translator or translator +.

The reason is that we all add cold air kits or different inlet tubes. And the one thing we don't do, that Buick did, was anchor the MAF down. So it now vibrates to death.

If you want your MAF to live longer bolt it to some kind of bracket attached to the car's frame.
