You have a bad ground for the air flow meter,check the black/white wire for a break.

I was thinking that myself so I cut about an inch off of the old plug-in installed a brand new plug with pins just to make sure I had solid connection

Where does the mass airflow sensor ground go once it goes into the harness do you know by any chance maybe I'll track back further

Are the camshaft sensor and mass airflow sensor on the same ground
