Audi A4 b7 130k miles

2.0T fsi

I noticed a couple weeks after I bought the car that the rpms were bouncing and the car was speeding up and slowing down as the rpms would bounce. The bouncing is more severe when the engine is still warming up. Rpms do not bounce while idling.

I can't seem to pinpoint a cause since I'm still pretty mechanically uneducated, so here I am, any answers would be great I'm pretty worried about the welfare of my a4.
