Hey,
for a few months now ive noticed that with light accelerator pressure my civic hx will occasionally suptter/jerk, and the only way to run smoothly is to either release all accelerator pressure or apply a lot more. there is no sputtering with heavy accelerator pressure, but in all gears (5-spd manual) it suptters with light accelerator pressure. does anyone know what this might be a symptom of, and how can i fix it?

thanks guys.
