Does anybody else's car do this? I've had it to the dealer more times than I care to talk about and they claim they can not duplicate it and these cars have a rough idle normally. I've searched the forums but nothing really pertains to the '08's. 
The car has 10k on it, this started when it had 5K |
The dealer claims a rough idle? Mine idles very smooth.
What kind of gas are you using, and where is it purchased?
