Re: 2000 Windstar not accelerating
No, it can't be a bad pulley or tensioner. Cause it would make a squeezing noise instead of rattle noise and it would happen whenever the load of engine since the torque of the pulleys doesn't increase with the torque of engine output.
It sounds to be a bad upper intake manifold (plenum). It's a common failure on the 3.8L engine. It's an inner baffle sound. It makes a sound similar to diesel engine, right? It should increase with the load/acceleration.

A Windstar without having the check engine light is not a real Windstar.
