Mass or volume air flow a circuit low input 1997 pontiac grand prix

SOURCE: 2002 pontiac grand am, idle fluctuates at cold start in parkp0102

Sounds like a vacuum leak. Do you hear a sucking sound? Check your vacuum hoses, around the throttle body and intake for the sound. p0102 can come on when there is unmetered air getting to the engine and it could be fluctuating because the idle air control valve is trying to compensate.

You need to change the mass air flow sensor, buy it online its cheaper, or buy it from your local auto parts store, usually it costs 100-200, the sensor will be located on/near the throttle body which is linked to the intake. then you need a t-20 torque bit to remove the 2 screws, open the engine cover, and its about 3 inches in length, its black in color, open the 2 screws with the bit and un-clip the one wire, then pull it off the intake. if you want to see why its bad/or how it could be bad, look within the sensor, there should be 2-3 little pieces of metal strands (sensor components) if they seem damaged/corroded/missing then thats your explanation of the engine light, simply put the new sensor in, hook up the clip, then screw it in, before you even do this whole procedure, remove the negative battery terminal, that way your computer resets and will acknowledge the new sensor, when your done with the new sensor install, put the negative battery terminal back in, SECURELY. make sure all connections are solid and tight. then thats how you professionally do a maf sensor swap. how do i know, changed my own sensor on my 1999 pontiac grand prix :) once your done with the procedure write a testimonial for good feedback ;)
