When rolling out of first gear the car begins to vibrate, tried giving more gas to make sure it’s not me and still the same issue. Does it while going in reverse too.

Good morning,

This sounds like the clutch is vibrating from hot spots on the flywheel. When that happens and you are starting from a stop, the car will vibrate. It usually does not vibrate shifting to second and the other gears once moving.

You will need to replace the clutch assembly along with the flywheel.

I attached a YouTube video from 2CarPros for removing the transmission form the car for you.
