First of all it's a 2.2kb car. Recently I developed a ringing sound that sounds like u just got flash banged in COD lol. It's a constant sound that only starts when the car is warmed up and idling. If I give it any amount of throttle it goes away. I'm unable to pinpoint it even though it's very loud but it's definitely coming from back of the engine. I used a stethoscope to see if I could hear it coming from the actual blower but failed to pinpoint it. Thinking it could possibly be from iac valve being that my f250 used to do the same thing but with idle symptoms as well. Any input helps. I will try and post a video in a minute.
