Has anyone noticed this? I seem to be getting a low rpm stumble immediately after pulling away from the service station. It seems to last for the first 50 miles or so. At first I thought it was a bad tank of gas but over the last few months it doesn't matter what brand of gas I use (I always put in 93 octane on the east coast here). It is almost as if I am getting a fuel cut off or hesitation upon load but at rpms <1800. It has a frequency of 1/4 second. It isn't nearly as bad as the jerking from the US software that people notice on acceleration. This is noticed by me on cruising say 40mph but then applying load as if going up a hill. It is concerning enough that I am urged to downshift when normally the torque we're all used to would not give us a second thought. Is this a delayed software adaptation thing? Poor fuel pump pressure? Need for repeat fuel filter (did that 80K miles ago)? Thanks, Dan.
