A bad oxygen sensor can cause the engine to run too rich o r too lean, leading to poor fuel economy and increased emissions. Understanding this issue can help in maintaining optimal engine performance.

Symptoms of a Failing MAF Sensor:

Poor Acceleration: The engine struggles to respond when you press the gas pedal.
Rough Idling: The engine may idle erratically, fluctuating in RPM.
Decreased Fuel Efficiency: A failing MAF sensor can cause the engine to burn more fuel than necessary, leading to lower fuel economy.
Engine Stalling: The engine may stall while idling o r while driving, especially when coming to a stop.

Have you noticed any performance issues like rough idling o r poor acceleration in your Hilux?
