Hey folks I pulled the codes. indicated throttle postion sensor, MB tech said the sensor is in the accelerator pedal, i replaced that and still have the same problem. car will barely idle and shuts off the moment i touch the accelerator.
2001 MB c240, any ideas? I'm going broke troubleshooting this thing so any help is much appreciated.

It would be worth cleaning the Throttle valve...also called a slide valve.
on he W203 its at the front of the engine (not close to pedals)
They actually sell a spray for cleaning these things, Its a solvent.
If the valve is not seating correctly you will get many errors and the idle/acceleration will suffer.

Good Luck
