Hey i've noticed that when im at full throttle or high RPM (4-5k) i hear a slight rattling as if something is loose. I believe my cousin (who drives a 95' T-Bird) said the same thing about his bird. My motor is fairly stock. Just a cold air intake . But it done that before when i first had it too. Nothing has ever happened or had probs with the motor. Just something ive noticed and thought nothing of it. But wondered if anyone would know what it might be for sure. Lemme know what yall think. Thanks .
