Stab throttle, car wants to die

[ajm786]

1999 Oldsmobile Eighty Eight LS is the car.

So, either at neutral or when the car is in drive, when I stab the throttle, it feels like the car wants to die, but it doesn't.

I plugged up PCMSCAN on my laptop, and monitored the spark advance.

When I stab the throttle when the car is sitting parked, the spark advance goes negative, and the car sputters, then kicks back up. I logged all of this, including all the sensors the software was capable of logging (which is basically all regular OBD-II sensors).

What does this mean? Is the spark advance supposed to go negative when I stab the throttle like this? Does this mean the wires, the spark plugs, or the ignition coils are going bad?

I appreciate the input. Thanks!

Here is a video of the car when it was idling and I would stab the throttle. The spike dips you see is when I stab the throttle, and it feels like the car wants to die, but it doesn't. This is the same thing it does when the car is driving, and I'm at a stop light, then I want to accelerate.

You might want to go directly to Youtube to view the video, as it's more clearer and larger than on here.
