Hi All
My old C200 - W203 (2003) estate exhibits the following symtons:
Cruises along OK when at constant speed but when I hit the pedal hard to accelerate I get a miss-fire and the management light comes on.
Reading the fault codes yields:
State: Historic
Selfadaptation of mixture formation at rich stop(Tendency of engine towards 'lean').

Clearing the code = easy but symptons return next time I accelerate.
I am told the likely (and frequent) cause is a decaying/leaking balance pipe buried underneath the "inlet/injector" side of the engine. Difficult to access but neither too hard nor expensive to replace. Once you've removed everything that's in the way.
Apparently the task is well described in the manual but can anyone point me to copies of the relevant pages
TIA
Wimphot

Thank you
Oh how I wish all Youtube videos were as succinct as the one in that link.
Is this a job you have done yourself? Did you hit any curves not cover by ecologicaltime.
And do you happen to know if there are any other perishable components that might need attention whilst I am "down there'
in the engine.
Thanks again.
