Could also be loosing oil pressure
It could be one of two things. cam sensor or the cat sensors. but you would need to really need the ecu read to find the code the ecu is giving. even a cheap code reader will do to just get the code that is stored. as you don't want to just be changing parts.
the check engine light is flashing to alert you to the fact that the engine has a missfire in the ignition system, don't continue to drive this with the condition or u can overheat and damage the catalytic converter.
SOURCE: car stalls pressing accelerator do not increase
is it fly by wire or does it have a throttle cable ,if fly by wire change the sensors on the pedal
SOURCE: 2003 c240 check engine light is on,car runs
HAVE CAR HOOK UP TO A DIAGNOSTIC SCANNER TO SEE WHAT CODE IS.MOST OF THE TIME IF CHECK ENGINE LIGHT COMES ON AND CAR STILL RUN FINE.YOU COULD HAVE EMISSION EVAPORATIVE LEAK.YOU COULD HAVE A SMALL MISFIRE.OR YOUR ALTERNATOR COULD BE OVERCHARGING OR UNDERCHARGING BATTERY.MANY THINGS WILL CAUSE CHECK ENGINE LIGHT TO COME ON.HAVE IT SCANNED.IT WILL SPOT THE PROBLEM FASTER.

I had a similar problem with my 1994 S420.
Before taking it to the shop check the following:
Distributor covers, Rotors and Spark Plugs. That's what my car needed. Before I did it two "specialized" MB mechanics wanted to replace the engine wiring harness ($1,000.00) and the other wanted to replace Air mass sensor, throttle valve actuator ($2,000.00) I hope that's all you need.
Testimonial: "You hit it on the head. Had same problem with my '95 S500. diagnosed as bad fuel rotors. Explained to me there is one per cylinder, and were all origi"

hi, unfortunately this is one of them how longs a piece of string things, you could purchase a code reader reset the error code but, what you have to think of is what caused it to do it in the first place, accelerating to hard should not cause an error ( i do it all the time in my car lol ) but it might be related to the 02 sensor getting to much unburnt fuel passing it which would cause the engine light to come on, though if the car is running as normal i doubt that will be the issue, i would myself on a car like that take it to the main dealer and get them to check it out, as buying an inexpensive code reader might not cut the mustard with this one, and parts being as dear as they are for merc's i would play on the safe side, spend a few bucks to save a load...sorry not much help
