Engine Shudder

[UTVitz]

Interesting you say it has developed the shudder. Mine has done it since new, which mostly occurs during a/c cycling, but can happed as the idle adjusts after coming to a stop. Unless it starts to stall the car I wouldn't worry about it, try a different brand of gas. I've only ever used Chevron in this car and it's always happened, not all the time, not every day, just sometimes.

the '08 sedan has done this from the beginning . Notice it at an idle . Have used CHEVRON Techron fuel injector cleaner with no improvement . The car does get very good mileage though . So rather leave it at that .
