wheel jerk

Can anyone tell me what might cause my 07-c-6 to drop rpm and the wheel pull slightly to the right while idling at stop lights.

Well it's not really a turn but i could feel the wheel tug slightly to the right. You don't think if the a/c engageing while at a traffic light that it's possible for the rpm to get low enough to cause the power steering to drag ?

If you are putting slight pressure on the steering wheel one way or the other, and the engine speed slows a little, the engine will add slightly less assist at that moment and the wheel could feel like it is moving slightly under your grip. This is probably what you are feeling.
