So in summary, the car feels like rocking 2-3 times before settling into a stable state which is accelerate.

1) I have check the throttle micro switch to ensure full contact with a click sound.

2) I have ensure MAFS to be clean and non-sticky with the help of Carb cleaner.

3) I have ensure all vaccum hoses are connected and non has cracked.

4) I don't really know how to check the transmission and I don't have a 2 ton jack.

5) OVP and all fuses checked and replaced. O2 connection under driver seat has been cleaned and corrosion free.

6) ECU not checked and I have no idea how to check it.

Thanks!!!
