Greetings everyone! I'm very excited about this site, as i stumbled over it researching issues with my baby. As I accelerate , it slows down with a vibrating, humming noise and hesitate as i approach 40mph. I really don't want to take it to my local MB dealer b/c they are a rip off. actually the problem began less than a month after my service A. based on the knowledgeable threads and the selfish mechanic that cleared the codes, it sounds like my Air Mass Meter. now the new mechanic can't read what the problem is b/c the chk engine light is not on anymore. I just don't know what to do and it looks like i might have to take a trip to the MB dealer.
Any help is greatly appreciated.
