Understanding a MAF fault
To cut a long story short with the MAF unplugged the car runs perfect, with it connected it sometimes won't accelerate/rev randomly.
BUT i've tried another MAF only to have the same problem (albiet another used one).
It's a 4 pin one so I'm assuming 2 pins are for the temperature and the other 2 to measure the airflow.
I'm trying to understand what's actually happening in order for it too be faulty. At the minute i'm assuming the sensor is reading there is no airflow? but wouldn't this cause the car to stall or throw up an error?
I'm close to buying a new one but got a funny feeling it's still going to do the same..
