Question about 1997 Mercedes-Benz C-Class
I have a C200 W202 1999. It was running fine, I started it the other day and the accelerator does not work! It just runs smoothly in idling speed but pressing the accelerator takes the rev up by 2 or 3 and thats it. Bascally I cannot drive it more than 10mph!
Can anyone please advise.
Try this. Turn the ignition to position 2 and leave it about two minutes(you should hear components moving/making noise under the hood). This should relearn the throttle stop(sounds like your vehicle lost synchronization). After that period of time, start the car and see if it helps. If not, then it will probably have to go to the dealer so they can use the computer to try and relearn it.

Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
