the question was how to know if its pinging. i posted the question as i dont know nothing about cars.. this forums helps newbie like me to know a bit.. i thought the rattling noise was from the trunk so i checked.. now reading about these pinging (and in certain circumstances e.g. accelarating) made me wonder if that rattling noise is the 'pinging' and not something from the trunk..
