My 2002 Ford Expedition was running fine and then all of a sudden when we turn it on it sounds like a motorcycle and it has almost no power, the rumble its out of under the hood. What could be causing this?
It sounds like an exhaust leak. If you're hearing it under the hood then it could be the exhaust manifold.
Don't drive the vehicle like this, you will most likely burn the valves.
