Rattle on decellaration

[Slipper]

Recently i have noticed when i slow down to a stop or am accelarating at slow speeds there is a slight raspy rattle coming from the engine, sounds as though something is shaking back and forth. Its only noticable when i go from about 10km to stop or stationary to slow accellaration, just wondering if this is anything to be worried about, i figured it may have something to do with the transmission operating at the low speeds so i'd just like to know if this is normal or not.
Thanks

coulb be the heat shields under the car, near the transmission, i took mine off because they were rattling when accelerating at low speeds
