Grinding noise at deceleration at exactly 4 and 5 seconds.
-The grinding/rattling noise happens when you let off the accelerator above 3,000 rpm.
-Also happens at cold startup for about a minute and then stops.
-I checked all the exhaust pipes and nothing evident to me is making the noise. Noise comes from the front of the car under the engine bay.
-I cannot figure out what it is.
Please let me know if you have any idea of what the noise can be. Thank you in advance.
