Old Bora started idling, five or six hundred and one, and the throttle didn't burn. Why?

This may be a problem with the throttle or oil supply.

1, throttle:

The air intake bypass through the throttle valve is controlled by the idle motor, which is turned off as soon as it refuels.

Air intake of normal electronic throttle. If the electronic throttle valve is not opened and closed normally, and there is no oxygen in the car, it will turn off.

2. Oil supply problem:

After the throttle valve is opened, the idle motor is closed, the oil supply is not smooth, the mixture is insufficient, and it may also stall.
