Car shakes and studders?

[sleepy2lazy]

I have a 95 gsx, with basically no mods except intake, bov, exhaust.
I was getting onto the highway, so i was going pretty fast to merge into the highway on 2nd to 3rd gear.

To the point, after I got on the highway and sped up a bit and slowed down, I'm not sure what happened but my car just started to shake and studder whenever I stepped on the gas. Even at idle, my car would shake and studder.

The engine doesn't die, but I am not sure how to explain it. I took it for another drive on the small streets, as I push on the gas, it starts to shake and studder. Highway driving, any time i push on the gas it shakes and studders. Coasting is semi decent to being normal, but giving it any gas makes the car seem like its gonna fall apart.

Anyone have any idea what this could be?
