Oh i thought it was manual, btw still it shouldn't behave like that, My Mira E;S used to do the same thing, the Car almost felt as it died, no pick, high Engine noise, awful avg. The culprit turned out to be Engine Oil, it was very thick, Black, low. I changed it and the Car came back to life, avg jumped from 7km/l to 17km/l
,pick performance all came back to normal , when did u change your oil last?
Just kidding bro, no need of it
