you need to have circuits tested to start with and if good test sensors.are they unpluged or have corrision on them
take out the MAF, clean it inside , the 2 resistors , spray in brake cleaner, use "Q" tip to wipe off, let it air dry, 10-15 minutes. then disconnect battery or reset codes with code checker, car should run fine and chk light out. I dont know anything about smog test, we don't have that here in Canada. SORRY
Agree with #1....you can clean the MAF sensor yourself.
