I was idling for about 25 minutes I hear a little pop followed by a constant low pitch noise. I then immediately shut the car off. I turned it back on and there is still the low pitch noise. I went to go drive it the supercharger is not kicking in and there is a real loss in power. I don't know what happen. I was reading the forum and im seeing it could be a possible IC Pump failure or air intake sensor. Can someone please let me know what I should do thanks
