ok so it just started a few days ago and at first i didnt even think it was coming from my car but it has gotten more noticeable and it bugs the crap out of me. you can only hear it when the car is idling and it sounds like this weird bublying kind of whirring noise...its really weird. also, when i shut the car off it keeps making the noise for like a second or two after the car is turned off...i have NO idea what it could be. i thought it might have been my intake but i'm sure it isn't b/c it sounds like it's coming from the passenger side of the engine bay. any suggestions??????????
