hi guys looking for some help, here is the problem I have a 08 ml550 55780 miles and after she is warmed up in drive at low speeds in traffic I will hit my brake come to a crawl and my idle would jump up to 1300-1500 rpm on its own as if I hit the gas and twice when it happened she stalled out on the highway, I brought it into the dealer and they said that they cant find anything wrong but this is definitely a problem, I don't want to hit anybody with it leaping forward.
I have and they have checked and there are no codes
thanks for any help walt
