2012 ss ls3 idle question
 

hey guys.... is it normal for the rpms to dip down every 10 seconds or so while idle say at a red light? doesn't get low enough to seem like its gonna die but you can feel the shiver

Hi there! If you feel like something may be occurring with your vehicle, the best thing to do is to get the concern diagnosed at your local dealership. They should be able to run a diagnosis and run your VIN for any applicable warranties for any concerns that you may have.
