The most common cause for a tip-in stumble from a stop would be the MAF (mass airflow) sensor, also check the sparkplug condition. and make sure the oil level is at its proper level and not overfilled.

 

When it comes to a MBZ, its sparkplug condition reveals a lot about what is going on with the engine and its condition, these sparkplugs came out of a MBZ with a stumble from a stop. There was also no CK ENG LT and a no-code condition. just a drivability problem
