Don't know about the gas pedal, but the "tinging" noise sounds like the heat shields on the exhaust. They rust and then vibrate which gives you the "tinging" noise. Check them. If they are loose, just remove them. You can do without them very easily.

Good luck on the gas pedal. Maybe someone will have an idea...
