Hello! I believe the problem is likely to do with the mass air flow sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-mass-airflow-sensor). When this sensor is at fault it will be sending a regular error inlet reading which will cause computer to incorrectly apply air fuel...

A faulty throttle position sensor can most certainly duplicate all of the symptoms that your Mercedes is experiencing, however a faulty fuel pump or even a defective mass airflow sensor can be the cause to these issues too. I have...
