I bought a 2000 protege (auto) and has only 34 K miles. It runs fine but when I stop on a traffic light or the car is stationary it makes an audible rattling sound. This sound is not their when I am not stationary. Not sure why it's there. Is it typical of Protege's to make such a sound. I also have a 03 Camry and don't hear that. Any info would be much appreciated.
