2000 v10. the truck idles fine. no check engine light. when I step on the gas I hear a massive rushing sound, and there is no power from te engine. The engine acts as if either the exhaust is plugged or I am stepping on the brake while flooring the accelerator. if I idle and slowly accelerate keeping it under 2000 RPM I can slowly get up to speed but again no power and the rushing sound continues. 175000 on the truck.
