A faulty MAF sensor can cause engine sputtering in the following ways:

Incorrect Air-Fuel Mixture: The MAF sensor measures the amount of air entering the engine to help calculate the appropriate amount of fuel. If the MAF sensor is malfunctioning, it misreads the air intake, leading to incorrect fuel delivery.
Performance Issues: Incorrect fuel delivery can cause hesitation, sputtering, and poor engine performance, as the engine is not receiving the correct air-fuel mixture.

Cleaning o r replacing a faulty MAF sensor can restore proper fuel-air mixture management and prevent sputtering.
