Hyundai Yashi 1.4 displacement idle speed 660 is abnormal.

Hello, the idle speed of modern cars is about 660, the standard is 668 rpm, and the new car Rena is also at this speed, which is normal. Japanese cars and Korean cars are not as idle as American cars, so Japanese cars and Korean cars save fuel and the gearbox engine is well tuned. This is normal idle speed. If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
