Hi, I just bought a new 2004 Saturn ION. The engine is making some kind of weird noise (like a flying UFO! like bu bu bu bu) sometimes. Here is exactly what happens. First I have to drive the car for few mintues before the noise starts. The noise also only can be heard when I am driving between 45 to 55 Km/h. While driving at that speed, when I press the gas pedal, the noise starts. If I take my foot off the gas pedal then the noise stops. If I drive faster than 55 Km/h then the noise goes away as well. It sounds like if the cover of something is loose. Or some loose moving part. anyone had such problem with their cars? or might be able to guess where the noise is coming from?
Thanks
