Mercedes-Benz C200: I have a C200 wagon, w202 1997 ,automatic,

This answer was rated:

I have a C200 wagon, w202 1997 ,automatic, when I start the car in the morning and starts up perfectly ...idles for 2 seconds and stops. I restart the car three or four times before I can leave the garage. The car is also very powerless especially when I go arund a corner ...come off the accelerator and than get back to speed up...there is a hole of a few seconds before the car regains power. some days I can go full throttle without the engine going over 3000 rpms. I have done a service, new spark plugs, oil, air filter, cleaned the air mass sensor with a special "air sensor cleaner" and made sure all leads are good and tidy.
My name is XXXXX XXXXX I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.

From what you have described here this may be due to a lack of fuel to the engine.If there is a lack of fuel this will cause this type of fault here and is usually caused by a failure of the fuel pump assembly itself.If the fuel filter wasn't replaced when the service was done I would start with this as sometimes this can restrict and may cause this type of fault here.The fuel pressure should be checked if the fuel filter has already been replaced or if it is replaced and the fault is still present.

Hi Pete

I have replaced the fuel change.

The pump is not an option as far as I would know...either works or not. That's right?

What about the fuel pressure regulator?



The pump can operate but may not be supplying the correct fuel pressure or volume as I have seen occur before,this can cause hard or no starts and lack of power when accelerating.My info isn't real clear on this regulator on this model whether it is on the engine fuel rail or with the pump assembly but if the regulator is failing it can cause this here as well.I would start with having the fuel pressure tested to see if this is a possible weak fuel pump.
