Slight twitch (miss) at idle

[steveieybee]

I have a 2009 G8 GT that have a slight twitch a idle and the RPM's slightly fluctuate at idle too. Is this common for the G8 or is this a problem?

As far as I know it's normal, mine does it too but no stumble when you hit the pedal. I do notice a slight lag in the remote gas pedal sometimes, like when I'm trying to pull out really quick and it gives it way too much throttle barking the tires or sliding sideways if it's slick out, thank God for traction control or it could get wild real easy.
