Re: New 2008 with weird noises from under the hood
The whooshing sound and the sluggish takeoff sounds like you might have an exhaust restriction. Just because it's new doesn't mean that there isn't something wrong.
Get a friend to help you check it out. One of the easiest ways is to have your friend idle up the motor, about 1500 RPM's, while you are at the back of the car. If you take your hand and move it toward the exhaust and it is EXTREMELY hot, like you can't get your hand within 18 inches of the tips hot, then your exhaust might be restricted. If this is the case then you can have your exhaust checked at the shop with a back pressure gauge. Hope this helps. This will also cause that whooshing sound, something on the order of a vacuum cleaner.
