Low Whistle at Idle
Hey all,
Has anyone experienced a low whistle at idle that matches the lobe of the engine? I have a 19 SS A10 for reference. My car has done this since I bought it, wondering if it’s normal. The whistle increases in pitch with rpm, but I can’t hear it other than close to/ at idle. My car is completely stock.

Not hearing it. Do you have the GM CAI, it comes with a throttle body spacer that has a protrusion into the airflow that is supposed to prevent whistling.
