Hello there, many different faults can cause the MAF sensor on your 1999 C180 to cause the car to run poorly. If the MAF sensor was replaced and the problem still remains than the most likely faults are a vacuum leak, wiring harness fault, or lean condition. A qualified Technician such as one from YourMechanic will be able to diagnose your Mass air flow sensor and make any repairs required to resolve the issue.
