I just finished changing the fuel filter in my 98 Gsr. After installing it I had the hood open and turned on the car, sounded fine until I turned it off. It screeches for a good second than sounds like a blow off valve. I dont know if it was always like that because I cant hear it with the hood closed. The car runs fine too and all the conncetions are tight, everything definatly looks right, but i could be missin something. Lemme know.

Thanks
