Ok guys, got a problem. recently I have noticed that when the car is idling it sort of chuggs and very slightly shakes the car every few seconds. And then when I get out on the highway the chugging gets worse and its more of a pulsing that shakes the floor board and gas pedal. its really annoying and hasn't ever done this before. Anyone else have this happen to them?

 

nobody?

 

I'd take it to the dealership just in case if it is something really serious.

 

Any thoughts on what it could be? before I take it in
