MAF issue

[White Ghost]

Hi I am new here and I did do a search first I just recently picked up a 94 Mazada Nav and I bought it knowing that it idled like it was missing. The cel is on and I hooked up a scanner and it gave me two codes one was 10 and the other was 157 and it also said mass air flow sensor voltage low hope this makes sense. Now before I go and buy a new MAF can anybody point me in the right direction on how to test the maf first to make sure it is the issue.
Thanks

I would try to clean it and then reset the computer.

I had read that took it apart and it was dirty, cleaned it pulled negative terminal off battery cel was still there. So going off the code saying Mass air flow sensor output voltage low I went and got a new MAF (a new Barometric pressure sensor already on it) today put it in and truck still ran rough but cel is gone. So for the heck of it I stated to pull out the spark plugs and the middle one on the drivers side the end that goes into the head was all corroded and part of the pocelin was missing not sure where it is but by the looks of the spark plug the only thing it was doing was filling the hole in the head so tommrow I am gonna go get some new plugs, fuel filter and some other things to give it a tune up air filter looks brand new..So we will see where I'm at tommrow.
