Noticed it for a few months now on my 03 WRX, 29k miles
On a slow accel, ive noticed a hesitation/sputter just after 2k rpms, and if it happens once, chances are I can drive around and make it happen a few more times, almost always at 2300rpms, but ive noticed it as low as 2k and high as 2500.
Its a sputter enough to make the car jerk (very noticable this morning, driving slow in the snow)..
Any ideas???
