Hi Mercedes Gurus
I have a problem with my car. I think I should provide more details as since 24 hrs no reply from any one.

I have mercedes E 200 1993 German model Petrol Car . Engine 124 model. Automatic Gear

I am having problems when i start the car in the first time the RPM fluctuvates . Means let say when i start the RPM is the RPM meter in between 5 - 10 . Once i change the gear from parking to Reverse or Drive the RPM level in the RPM meter drops to let about 5. It slowly starts giving engine jerks , if i didnt raise the esclator sometimes engine stops. Again i have to start the engine.

Same thing happens if i am stoped at Trafic Signal and A/C is on. If i Switch off A/C when it's stoped at trafic signal then RPM comes in between about 5-10 range.

but once running started no problem.

When i show this to mechanic he is saying there problem with ACTIVATOR ( I dont know the name i specified is may be diffrent than the general name, but mechanic told its called ACtivator) which controls all the RPM and sits next to the Engine..

HE is advising me to go for Used one as new is quite expencive here,,

I welcome your suggentions and advice..

Anticipating quick reply. Thanks in Advance
