My symptoms were a slight stumble or roughness in 3rd through 6th gear when accelerating in the 3000-3500 rpm range. I assume it was there in all gears but the car accelerates so fast in 1st and 2nd that it isn't perceptible. I cleaned it with small brushes, gun cleaning patches and carb cleaner and the symptoms were immediately gone. I would say I was able to remove about 70% of the buildup. Next time it will be walnut shells.
