I have an 05 hatch. Non turbo 3.

While accelerating, the car very violently jerky back and forth. More in the lower gears. I'm afraid to even drive it because I don't want to do any damage. It feels serious

Brand new spark plugs. Coil packs are good. I'm not showing any codes

I used to put "pre-gapped" NGK plugs in my prior car (Audi A4) and I always checked the gap and found them to be a lot wider than expected. I ended up re-gapping them myself before installing. Check your plugs.

Will do. Thanks for the advice. What should they be gapped at?
