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.

i dont know if it is in the pedal. but the throttle position sensor is apart of the electric gas actuator or throttle actuator. I have to replace this on my car too as well as the Mass Air Flow meter. I will not let the dealer put these parts on as they are incompetent and I have been taking my car there for the same problem several times. they have fixed wrong things i guess so i will tire of the car and get another one. If i do this what MB dealers need to realize is I am not buying from them or another MB given the horrible services. Call around to parts places and Inde Mech and find out if it is in the pedal, which I doubt. try if you need the Mass Air Flow Sensor/ Meter as well as the Throttle Actuator.

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
Joe

are there any pictures of the location of the throttle valve actuator?

i was driving my ml350 last night and hit a big pot hole and thats when my acceleration on the car started to give me issue it would take a few seconds before it response. So i parked the car turned it off and turnn it back on and the check engine light appeared. Now the car will take like 2 seconds to accelerate. Got home woke up this morning still the same issue. is there anything i can do without seeing my expensive mechanic and if not what should he be telling me

I have the same problem on my CLK 320 W208, What I do to solve this problem is to disconnect the battery for around 10 min and then connect it again. Problem vanishes but with me, all the time I hit a considerable pot hole while accelerating, problem comes back
