Hey I have this issue with my mustang that just recently started. When I give the car full throttle there is a loud rattling sound that comes from the under the hood I think. It only happens at full throttle and no other time. It doesnt seem to happen when I just rev the motor up so I was wondering if you might have an idea of what it is.

Hi there,
you may be having a problem with valve bounce, this is common when engines are over revved, to over come this you will need heaver valve springs,
