Once I put "Drive", the RPM drop down to 500 to 1000 rpm. This condition make me unconfortable driving the car and other impact make gasoline much more consumed. For info: I have replaced the throttle valve due to car engine drop suddenly while I was driving, and multi core cables look bad. How to maintain the RPM in idle position to around 750 RPM and also not having big difference while we are in 'Drive" mode. Thanks.

There can be a lot of causes. From what I know, the idling cannot be adjusted manually. The idling is determined by the ECU. You have a European Mercedes C200 W202.
1) Air leak. Check the valve body and trace ALL the tubings around it. Most of those hoses tend to be brittle in time.
2) Clean the butterfly valve and use a fuel injector cleaner and those spray-on carb cleaner.
3) Dirty air cleaner.
4) Gasoline related. You may have used a new gasoline brand. the best is to use a higher octane gas.
5) Faulty spark plug. - inspect it if it is sooty.

On the US version MBz cars there is an IDLE SPEED ADJUSTMENT screw just under the left side of the air cleaner when standing in front of the car. I assume you are talking about a gasoline powered MBz c200. Adjustment s/b done when the engine is warm and the transmission in neutral.

Lower your idle speed with the screw on your fuel injector - should be a flat screwdriver headed screw standing alone and close by your fuel line... for exact locations, you can find detailed diagrams on the net. Once you find it, don't be afraid to play with it a little, and turn the idle screw while it's running so you can hear the engine speed get higher or lower.
If this doesn't work, I'd have someone check your fuel injector for a leak...

it somewhat is commonly commonly used, it somewhat is performed by potential of the pc so the engine warms up swifter, except this in simple terms began performing this way, it somewhat is commonly used. Forgot to ask what length of engine, for a V8 and V6 this may be slightly severe, for a 4 cylinder this is not overly severe.
