Guys, my persona 2007 auto engine dies when I reverse. Then when I try and start, it's like trying very hard to keep the engine moving, then engine dies again. And when I finally able to start it, rpm unstable and jerking like hell even when it's not moving.

Changed the petrol pump but still same thing. Then mechanic told me there is a error code P0170-5D: L-R short term adaptation.

Haih, don't know what's wrong with my car. Anyone faced with similar situation before?

My persona was jerking when i'm driving at speed of about 80-100, it's like not enough fuel / power, suddenly cut off, have to slow down abit, then only back to normal. Checked with the pdt tool,it says map sensor low voltage. Anyone encounter this problem before? Mechanic told me got to change the whole throttle body.
