Mine does it too. Once it warms up it wont do it again until its cold. I've seen a few threads where it seems pretty common but can be tuned out. I worked with my tuner and we got it better but not 100% correct. When I start to feel it stumble I barely tap the gas a few times and it helps quite a bit.

If you watch your AF you can see it start to run rich and you'll know when its about to do it.
