Well Got my first car last night in Tallahassee, Florida for thanksgiving (97 Mercedes-Benz C230 that looks brand new!). No interrior Damage and no dirt whats so ever on the engine paint it is great condition too (black). Anyways It runs great at 1500+ rpms. Every so often when I come to a stop, it idles rough and tries to shut off. Sometimes if Ibump the gas it wont shut off on the times it reallllly wants to. Could this be the Mass airflow sensor or the O2 Sensor??? HELP appriciated before the benz dealer tries to get more money than they need out of me. Also can it be a "Do it yourself" job with little experience with cars?

Thanks for helping a Mercedes newbie

Forgot to mention I did drive it today for about an hour and it cut off on me at walmart and another redlight. But I purposly didnt do anything to prevent it cutting off just to see if it would do it.

 

Engine light is on.
