2000 Dodge Stratus Repair Question
Whistling within the engine
What you have is classic vacuum leak- the pitch changes coincide exactly with the vacuum level present in the intake. Look first carefully at all the vacuum hoses, looking for cracks or collapsed lines. But I tend to lean more toward intake/ pleneum gaskets- given the tempature of the engine is relevant to the sound. Listen for the sound source, and spray suspect area with a non flammable cleaner ( mass air, etc) using the little tube on can. When leak area is found a noticeable change in sound will be heard. If it does, it needs to be rescaled with new gaskets. Hope this helps, Doc
