Bad mass air flow senso possible?
I recent had my maf, wb, and fuel trims go crazy. I am getting the maf circuit code, and the wb and maf are showing super lean but the fuel trims are not that bad. Is this a sign my maf sensor is shot? I tried increasing the ve and maf tables but its still going lean. Also I know noticed sometimes after the engine has reached operating temps its not going into closed loop all the time. Any help on what this could be would be appreciated.

Mass air sensor gone bad possible?
Here is the tune. Again I tried raising the map and the ve to see if the maf and the wb would go positive but they didn't im thinking it the mass air flow sensor. Let me know your thoughts. Thank you again. car was giving the symptoms. Bucking and struggling to idle all of a sudden.

Update. I up the fuel trims by 10% and zero out the idle air coolant lower table and its still stumbling. Maf code came on again and one point on the scan one of the narrow bands bottom out to zero and hung there. Could this be a bad 0xgen sensor as they are brand new with the maf? Could there be a fuse for just the maf thats going bad or maybe something mechanical has gone bad on the motor thats causing the maf to act up? Any thoughts on this is appreciated.

Follow up. Finally got a solid sign from the scanner. Went to get gas and after cranking the car back up. Maf code was thrown but this time the maf and the wide band went lean together. Could the 3pin to 5pin adapter maybe have gone bad. Any thoughts are appreciated. posted pic of the adapter I have been using and scan.
