I have a 09 Subaru WRX and when i'm slowing down (be in second gear usually) and let off the gas, i'll get a rumrumrum sounding noise. Then i'll give it some gas and it will still make it for a tad till it gets up to some speed and the noise goes away. Is this normal? or should I have it looked at. It doesn't always do this.
Any help be greatly appreciated.
