maf sensor test? car still runs the same with it unplugged

I ended up wasting 300 bucks on a perfectly good working part. The problem ...

The mass air flow sensor is a possibility...try leaving the mass air flow sensor wire harness unplugged to see if the car runs better. If it does, probably it is bad. However, I would also check the exhaust for a restriction (eg. cat converter could be plugging up), one way to check that is to hook a vacuum gauge to the engine to see if you get normal values. (vacuum should hold steady @ about ...

Car Runs Better Without Mass Air Flow Sensor –

Car runs better without mass air flow sensor. If you disconnect the mass airflow sensor then the car should keep running and still be able to start normally.

Its when the air duct that runs from the air ...

Why does my car run better when I disconnect the maf sensor?

The MAF sensor measures air weight in grams per second and air temperature and if either of those two are off then the ECU may command a leaner or a richer mixture. By disconnecting the sensor the ECU switches to limp mode and the car may idle better. Some MAF sensor wires can be cleaned and some cannot as the wires are not easily accessible.

This means that if your mass airflow sensor dies completely, then your car will stay running and surprisingly the car might run better without the mass airflow sensor. That is because if the sensor is bad or giving a wrong reading, then the cars guess might be closer to the actual amount of air that the engine is getting giving you a more accurate fuel mixture.
