When you press down on your gas pedal, you expect your car to provide the horsepower you need, but one day, that might not happen. There are a lot problems that could arise, especially if you do not have your auto care specialist maintain your car regularly. One of those issues is hesitation when you accelerate, which could be due to your MAF sensor.
Detecting Issues With Your MAF Sensor
The MAF, or mass air flow, sensor helps your car's computer regulate the amount of air needed for your engine. This is important information so that your computer can request a specific amount of gasoline from your fuel pump. The ratio between air and fuel is essential for proper combustion and the overall quality of your drive.
Yet this sensor could fail you, and one of the common symptoms is hesitation or jerking when you accelerate your car. The jerking or hesitation will likely not occur if you are cruising at a constant speed.
Problems with your mass air flow sensor are also associated with the following symptoms:
- Your check engine light might turn on from time to time.
- The idle speed might surge or drop too much. It may also feel like your car is going to stall.
- You start to see dark gray or black smoke coming from your exhaust pipe when you speed up.
- The fuel economy that you are used to might suffer.
Be sure you talk to your auto care specialist about these symptoms so that he or she can help confirm your suspicions.

You will need the following:
- Your owner's manual or repair guide
- A new MAF sensor that belongs to your make, model, and year
