Low speed throttle surging?

I was making a slow sharp turn this morning and I felt the car surging at low speed with noticeable throttle fluctuations. The car is stock other than an AFE intake which was installed yesterday. Is there a correlation? If so what could cause this?

I ask because others have mentioned seeing their RPMs bounce while idling when the car is cold. FYI my car was still cold (ie only driven 2 miles after startup when it happened). Any and all input will greatly be appreciated.
