What is a common sign of a malfunctioning MAF sensor?

A malfunctioning Mass Air Flow (MAF) sensor can significantly disrupt the air-fuel mixture that is crucial for engine performance. When the MAF sensor is faulty, it may send incorrect airflow data to the Engine Control Unit (ECU), leading to an improper fuel calculation. This results in a lean or rich fuel mixture, which can manifest as poor acceleration.

This issue often arises because the engine is not receiving the correct amount of fuel needed to match the volume of air entering the engine. Consequently, the vehicle may hesitate or struggle to gain speed, impacting overall driving performance and indicating a clear link between the MAF sensor's functionality and the vehicle's acceleration capabilities.

Other symptoms, like excessive smoke from the exhaust or frequent misfires, may relate to other engine issues rather than the MAF sensor specifically, which is why they do not serve as common indicators in this context. High fuel pressure is typically associated with fuel system issues and does not directly correlate with MAF sensor problems.
