Just replacing Cam Sensor and Knock Sensor in the repair shop and they also do some test with diagnostic tool T605,there is no problem with the car.
But After less than 20 miles 's drive, there is a very high pitched squeal when I mash the accelerator. The more I accelerate, the more the sound
becomes like a very shrill whistle. The sound is coming from under the hood on the driver's side. Does anyone have any ideas?
