My husband and I recently purchased (about a week ago) a 2008 Dodge Ram FlexFuel truck with 63000 miles. Carfax was clean and showed the vehicle was regularly serviced by the dealership. Within a few days we noticed the truck lightly jerk while driving down the road. Was on cruise and pulling a hill so initially thought perhaps it had to do with the cruise. Now the truck has an intermittent rough idle when in park and an intermittent jerk when maintaining speed on a highway or pulling a hill. The truck has not died, has no error codes, RPM's never change and shifts just fine into gears. The rough idle in park is not so bad (noticeable but not awful). What is most bothersome is the intermittent jerk while maintaining speed or pulling a hill. We have not noticed a jerk or a decrease in power when accelerating.
