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,
