Vibration at idling speed
|
Saab 9-3 (9440) M03- with engine alternative B207
In certain cars, vibration may arise in the body at idling speed and when the car is stationary.
Certain cars, equipped with automatic transmission, may have idling speed set too high, which may mean that the car moves forward too forcefully when lever position D is engaged.
In the case of customer complaint, the following procedures must be carried out.
