Idle speed
My s280 w140 idles at 750 rpm when in park or neutral. This is fine, but when i engage drive the revs drop to 500 which causes problems. When i stop on a hill the car does not stay still but starts to roll backwards and i have to feather the throttle. I have been told that it is the vacum modulator on the gearbox, can anyone give me some advice as to what might be causing the problem.
Many thanks Lester. |

What year is the car? The 722.6 transmission will allow the car to roll backwards down a hill in gear 1. Does it run smoothly when at idle in gear?

Idle speed
My car is a 1995 and the engine does run reasonably smooth although 500 rpm for most engines is asking a lot.
Many thanks, Lester |
