rattling

[chrisE318is]

right not sure how to explain this but basically when driving normally my cars fine but when i put my foot down and let it rev round once stopped theres a loud rattling from under the bonnet, seems to be at the front, turn it off and straight back on it stops. im not sure if its a pulley or chain ratting ive chainged the tensioner but dont know when the chain has been done. just seems strange how it only does it when i put my foot down and can stop straight away. is this usual or just me? and can anyone tell me what it is?

could be anything dude! Try reving the engine from the butterfly on the throttle body under the bonnet then you might see whats rattling or roughly what area its coming from
