For some reason evrytime I have my foot on the gas theres a high pitched tinging or pinging sound. Sorta like a rattle coming from infront of the passengers foot. This only happens when accelerating. The instant I take my foot off the gas it stops. As long as the foot is pressing down the throttle it makes the rattling noise. Anyone else experience it? It doenst matter if you mash the pedal to the floor or if you press it down gingerly.
