I would try cleaning the air flow sensor. When you say removed -- do you mean taking it off or just unplugging it from wiring harness? Also check and clean air filter.

Oh ok. That leads me to think that the sensor either needs cleaning or to be replaced. I would try cleaning first. Only use cleaner for that type sensor and make sure that you don't touch any parts of the sensor with your hands.

I have replaced more than 3 sensors,replaced the GDI pump,replaced the fuel pump as well as the plugs. Now I am to check my ECU
