1994 Mercedes-Benz S500 ProblemsFaulty Mass Air Flow Sensor Causing Erratic Engine Operation and Poor Fuel Economy
A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.
Problems with the pneumatic system can cause closing assist and door lock issues.
One or more door windows may stop working due to a failed window regulator. Replacement of the failed regulator will be necessary to correct this concern.
