From my experience its quite a common problem....I've had to replace 2 fuel distributors on seperate 300E's in the last two years.

Over a period of time they do get clogged with crud from the fuel lines, which leads to hard starting, uneven idle, stuttering from low revs etc.

You also tend to get overfuelling as a result, so it may be worthwhile pulling out the plugs after you have let the car idle for a period of time and see if any of the plugs are wet. If they are its a fair bet that the distributor is playing up.

Personally, I blame both replacements down to the fact that I used injector cleaner soon after buying each car....shortly after that the stuttering began. I can only presume that the injector cleaner scoured off the crud in the fuel lines which then got stuck in the distributor.

I got replacement distributors from Mercedes breakers and replaced them myself......they are not hard to change...just remember to fit a new "O" ring to the replacement distributor and never use fuel injector cleaner!!

PS: it can't have been the quality of the fuel that caused this for me, as we run on 95 Ron as standard over here.
