I have a 2002 Black Accord. I bought it last August. I have notice lately that when I come to a complete stop the rpm needle will go down and it feels like it will turn off, but it doesn't. I have only felt it shake one time. I put it on park, I give it gas and the needle will go up, and then back down again. But once I put it on drive, and I drive its fine. After driving it for over an hour its fine. It doesn't do this while I am driving.

Sometimes it will do this and sometimes it will not. My dad and brother has driven it and they haven't notice it.
I also notice that it happends when I am coming home from work.
Doesn anybody have an idea of what it be..?
Thanks
