On the car you are asking about, mass air flow sensors are used to measure the amount of air moving into the throttle body. The value it measures is used by the powertrain control module (engine computer) to calculate the correct amount of fuel to deliver through the fuel injectors for the optimal level of all-around performance of fuel economy, emissions, and spark plug life.

SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

SOURCE: CODE PO102 after Mass Air Flow Sensor replaced

Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

Mass air flow sensor maybe drity or going bad . Ever had it replaced ? Have you replaced the air filter lately ? Video's on youtube showing how to clean mass air flow sensor , you would have to buy a can of mass air flow sensor cleaner . Also while your at it clean the throttle plate , again there are videos on youtube . How did you check fuel pump ? To do it right you would need to hook up a pressure gauge . Also check flow .Videos on youtube .Has the check engine light come on ? Also you mite try some fuel injector cleaner and or dry gas for moisture in the fuel !

    Lost power and when we started it it wouldnt get of idle now it wont start it sound like it wants to start


    You would need a fuel pressure gauge and the attachments to hook it into the fuel line before the injectors.
    You can spray carb cleaner into the throttle body to imitate the injectors, just don't spray it thru the mass air flow meter.
    Its possible the mass air flow meter was failing and your cleaning it finished the job. They are very precise components. There could be an air leak between the throttle body and the MAF meter.
    You could need a simple fuel filter too.
    If it will start on carb cleaner and the filter is good, you may have to get a book to troubleshoot the mass air flow meter.
