ok if the car is in gear it and i let off the gas all the way around 4krpm it starts to make like a noise that gets a little bit louder around 3k rpm and starts to quiet down by 2k rpm it sounds like it might come from the driveshaft.. my integra made a noise goin in reverse you all know that noise the gear wine its kiiiiiiiinda like that but a little deeper and not as loud... its pretty hard to explain.... the car drives perfect just that noise is annoying
