I have a 2000 ML430 that runs really rough until 35 to 40 mph. After 40 it runs a lot better but still doesn't have the acceleration like it should.

Asked by Oct 07, 2015 at 10:38 PM about the 2000 Mercedes-Benz M-Class

Question type: Maintenance & Repair

I have replaced all the catalytic converters
and fuel pump but the problem still
persists.  There is the egg smell too that's
coming from the new converters again too.
The car ran great then all of a sudden one
more it started acting this way.  Any help
would be greatly appreciated.

That is expensive just guessin' what the problem is- take it to a good Mercedes mechanic- a GOOD one- and pay the premium- it will still be cheaper than guessin' and a lot less hassle-
