I have a Mercedes ML 430 from 2001 Gasoline and the engine was losing power when pressing on the gas pedal. I replaced the airflow mass sensor and the issue seemed solved however after a couple of days the engine started having no power after ignition. If I leave it for a couple of minutes to run and get warm it works fine, however the first minutes I'm not able to put get any RPM hence get the car on the move. at all. Any idea of what could be the issue?
