Th MAF(mass air flow) sensor is needed for the car to even start. It measures the air being taken in and injects just the right amount of fuel to run the car.

Gas powered cars Usually get tune ups around 125,000 miles. MAF sensor can be cleaned using a special MAF cleaner you can buy. If the MAF is bad then you see bad fuel economy, bad acceleration, and maybe even a check engine light.
