I agree that they can be troruble, but I just had the head redone in September and the rought starts continued.
I have planned to have my shop replace the injectors for me but have not had the time ( or taken the time) to do it yet. This one of those problems that won't stop you from driving and enjoying your car, but you know you should take care of.
I keep hoping that I'll find some information or diagaram or something that will clear up how to do this job and allow me to confidently do it myself. But alas!
Anyway....thanks for the input. This forum does great things for MB cars and their owners.
