Just got my first Subaru ever, have always owned a Honda, but have been less than satisfied with there new lineup. I picked up a 2014 wrx hatch at the stealer. My question is while the car warms up and does it's idle thing it seems to sway in the cabin (left to right) just enough to notice. Is this normal and the nature of the motor? I assume it's just the beastly motor under the hood doing it's thing. (There are no cel, and do not seem violent in any manner like a misfire) However, like I said I am new to Subaru so I really have no clue. Thanks for the help in advance to those who can offer guidance.
