The engine sounds fine when accelerating and decelerating, I do regular oil and fluid maintenance. Now it sounds like a “tight”vibration or a deep whirring sound when the car accelerates during a climb or speed increase. Is it something loose or is it more serious?  Could it be the muffler???

  1. Could be a muffler or a worn drive belt.
