Can a malfunctioning MAF Mass Air Flow o r O2 sensor cause the Alsvin’s engine to sputter?

Are faulty sensor readings creating a lean o r rich fuel mix, which could lead to uneven combustion o r power loss, especially under acceleration?

Yes. Faulty readings from:

MAF sensor → miscalculates intake airflow, causing lean o r rich fuel delivery.

O2 sensor → misreports exhaust content, affecting ECU fuel trims.

Either issue can lead to poor combustion, sputtering, o r CEL Check Engine Light.

✅ Scan for codes like P0101 MAF o r P013x O2 sensor using an OBD-II tool.
