Atsl throttle normal sound

Quiet, no noise. Cadillac ATSL adopts advanced active sound insulation and noise reduction function, which can effectively reduce noise and vibration. Normal sound is quiet, without obvious murmur or noise. If there is abnormal noise, it is because the throttle valve is dirty or damaged, which leads to poor air intake into the engine and affects the combustion and performance of the engine. At this point, it is necessary to clean or replace the throttle valve.
