I just got back from military duty yesterday and drove my car for the first time in two weeks. I was driving with my wife and noticed that my engine sounded different somehow. I listened closely from a red light. I hear a flutter in first gear about 1800RPM to 2200RPM and about half of second gear up to 2200RPM. I don't think it could be a header blown, the car does not drive rough, but I am not sure. I have blown an engine before (Cougar auto 4cyl) and it did not sound anything like this. What could it be?
I have uploaded a sound file. You can hear it best at 2:32-2:50 and 3:19-3:27.

I use VLC player to play AMR files, I dont know if Windows Media Player can play them.
