Ok so I am wondering if this is just normal. I dont recall feeling this when i got the car. I dont drive it often. its a 2012 WRX I only have 2000 miles on it. When i am idling the car has a very slight rock back and forth to it almost like it has a really mild cam. I just dont remember it doing this before I always thought on idle it was smooth with no car rocking. I dont beat on the car and its stock except for a nameless axle back. I never seen any CEL just curious if its just a normal thing and maybe I just didnt notice it before.
