Is the car stock or any mods such as intake? P0102 DTC means MAF sensor low frequency. Possible causes are blockage at intake screen, vacuum leak at the intake manifold or throttle body, EGR valve flange leak. Also a defective or improperly sealed PCV valve. Try cleaning the throttle body.

i found that online
have you tried putting in a new MAF? sometimes these things just go bad.

try picking a lower mile sensor from a junkyard.. should be cheap
or evan a new one..not sure of cost but atleast this way you can eliminate the possibility of it being a faulty sensor

It is stock. A couple people say try the MAF which is of course expensive so I will be junk yard shopping for the next couple of days! Thanks!
