what would happen if you start car without maf sensor plug connected
Can you drive without a mass airflow sensor? The MAF sends readings to your computer, which then uses them to adjust the mixture of fuel/air in the combustion chamber. If there is no MAF you will be getting all kinds of misfires and very bad fuel economy. In the long run, it's probably cheaper to replace the MAF. You can also try spraying the wires in the sensor with some carb cleaner. Alot of the time the MAF is just dirty and doesn't actually need replacement. EDIT: Ooops, I meant contact cleaner.
