I'm not too worried about it though given that it only happens for me when the engine is stone cold and at very low speeds.
Ok wasn't sure what you guys were talking about, but I get the bucking too. As long as you wait for cold start to end (aka around 15 seconds after starting the car), the issue isn't there.
