hey
i have a '99 mercedes benz ml 320 that every now and then (this past month like 3 times) just stops as if the spark plugs get completely screwed up. Thing is they are fine and I have replaced them a couple of times.
Every mechanic I see doesn't know what the problem is and even suggest there is no problem. Its pretty annoying and even unsafe. I am not really an expert so any help on what it could be would be appreciated.
thanks
