O2 sensors? Does the exhaust smell bad at all (I.e. Running rich)? Once it's warm it should go into closed loop and just use the O2 sensors for fuel metering.

Hello, I am having the same issue with my c280. Once it warms up the car starts misfiring at stoplights until I put it in neutral. I was just wondering if you found a solution to your problem that I could try.

check for vacuum leaks
