Well its definitely the #3 cylinder. I just pulled the wire and it runs smooth again ( i'm a dumb a$$, I should have done that on the drive home, it would of went WAY smoother/quicker lol.)

Sounds like crossfire. Try replacing the distributor cap (and rotor) first. (There may be carbon tracks inside the cap that's causing #3 to fire on the intake stroke when a nearby cylinder fires.)
Second possibility is bad plug wires. Try watching the engine when it's dark ... you may see blue spark between plug wires. (If so, I'd recommend a complete new set of plug wires.)
