Has anyone experienced this? I come to a stop, then press on the gas to go
and I get some weird sound kind of like a waterfall from the air vents. It
doesn't last very long. Just long enough to shift to 2nd gear. I am not
listening to any relaxing sounds of nature CD either. My Altima is a manual
transmission if that makes any difference. Any help would be appreciated.
Thanks.
