Can anyone tell me if it is normal for the engine when warm to have a slight stutter. The revs appear stable on idle but doo drop slightly lower the longer it is left but stay visibly constant. However i can feel what is like a slight misfire through the car itself. Does not cut out or appear to be causing any problems, but this is my first impreza and i am use to a very smooth running type r.

Also i have noticed the brake feel quite heavy. Again i am use to a light type r with very light and responsive brake pedal, but on the impreza the braking seems to require quite a bit more effort, as in weight put on the pedal. It stops brilliant and i have not yet noticed any ABS interuption as i use to on the type r in slippy conditions.
