sort of off the back of this, my throttle does the same and I will have it all apart to have a better look but I found that occasionally when I have the throttle fully open it sometimes slightly hesitates but worse when I let off the throttle it slows then some times stops decelrating and actually sticks at the same speed (so I am letting of the throttle it slows then can stay at the same speed even though I am letting off) Any idea what that might be?
