for videos of the problem hanged mass air flow sensor
Changed crank shaft position sensor.
Changed throttle body sensor
Changed I a c (idle air controller).
Starts rough, idle evens out, in park or drive or reverse as soon as you hit the gas it stalls out.
Fuel pump and fuel pressure regulator where changed in fall.
We located the idle screw (see picture) and we turned it completely around slowly almost 5 times and it made no difference. We were trying to see if we could get it to not stall out.
This seems really irregular as it should only need tiny little movements
