I've noticed when I'm starting the car in the past three weeks it idles at 1200RPM for a few minutes and makes a loud whirring noise (almost sounds electrical) and then suddenly stop and goes back to normal. The ECT Sensor has been replaced with the revised improvement (Genuine OEM) as I know this is a common issue - this didn't fix it. Anyone have any idea or experienced the same thing? The car still boosts fine and everything, just on idle.
