M nissan frontier wont start with the mass air flow sensor hooked up but when its unplugged it will start and idle but i have to give it full throttle to keep it running, i got a new mass air flow sensor so what could it be?
What is your question?
It runs rough when it starts but i have to give it full throttle and my rpms dont go up like they should. Will start with maf sensor unplugged but have to give full throttle. New maf sensor.
What makes this problem better or worse?
Will start with the maf sensor unplugged

The mass air flow sensor that was in the vehicle in the first place was probably OK. Engine performance diagnostic testing is needed to figure out what is going on. I I would agree it's likely air - fuel ratio concerns.
