I just bought this truck. It has a factory engine with less than 500 miles on it and appears to be working great. However, from somewhere behind the engine I hear a high pitch scraping sound only when I touch the throttle. It doesn't seem to be affected by engine rpms necessarily; it may be affected by speed but this is hard to discern with accompanying wind noise. Again, any time I lift my foot from the accelerator it stops. It is very noticeable at 5-10mph when there are walls nearby (echo) and the windows are down. It sounds like very thin metal or like when a stick has gotten wedged and is being dragged on the ground.
