Can somebody help? I'd like to start this by saying that I know that the problem I am going to describe has nothing to do with the air intake scoop.
After getting off the interstate in my 2003 SL (15K miles) a month ago I came to a stop at a red light. When I accelerated at green, I heard a grinding/rattling noise (almost a plastic type of sound more than a metallic grinding). It happened at low speed and went away. Since then, I noticed that it happens a lot when turning and accelerating. At first it sounded like it was coming from the right side of the car, under the passenger's feet. Now it sounds like it is coming from under the car/engine, not necessarly to the right.
Well, since then (and I don't know if they are related), I experience a noise when accelerating and it is different than what I describe above. When accelerating from a stop or low speeds, there is a sound that sounds like a smaller engine accelerating. It goes away after I get past the lower speeds. If I stop and rev the engine, I can hear what I can only describe as a noise similar to that made when an exhaust pipe has a small hole in the muffler.
What makes this worse, is that it is not consistent. However, it does happen daily. The Nissan dealer has heard both noises that I describe and has done nothing to fix them. Their best advise is that it is the gas. I know what bad gas sounds like and this is not it.
I am getting very frustrated with a car I like very much. I'm hoping someone here can give me some advise that I can take to the dealer (preferably the solution).
