This just started a few days ago. At around the 2300 rpms and up I hear this obnoxious vibration or kind of a chattering even that sounds like it maybe coming from somewhere under the hood but can't pinpoint it. I opened the hood and listened to it idle and didn't hear anything. Maybe someone has had a similar issue? There's no performance loss and I can hear my turbo and it sounds pretty healthly. Sorry I can't be more in depth, just thinking maybe there's a few things people can have me check for that would vibrate at higher rpm's. Thanks in advanced.
