Got a flat battery yesterday, had to jump start car and buy a new battery now the car almost stalls with no acceleration, idle rate drops below 500.Really handy at intersections! Anyone know if this is a computer thing or got a quick fix for me - sick of spending money!

I have the same problem with my Galant, after sitting at the lights for a while or idling up-hill.Kind of sounds like its going to stall as you said.I know that my car is supposed to use 98 octane petrol but it is only using 95 atm.

Try cleaning out the throttle body, plenty of videos on youtube about it.

You might want to get used to that, sorry to say.

most grandis are GDI and will have elctronic throttle, if you tru to clean it out dont push on the throttle butterfly to open it as you most likely will break it internally. take it off and do it that way.
if its not gdi, then you may possibly have an idle speed control motor fault. if after cleaning it is still wont idle. (disconnect battery when cleaning).

GDI im guessing. prob throtle body needs cleaning. since its only happened after the flat bat maybe pop in to mitsi and get them to do a reset. i had the same problem, a reset helped, then had 2take it back to 4 a throttle body clean

how far have you driven it. This is commen in mitsis when the battery goes dead flat. It will come right after a while if it was alraight before the battery went flat. You could try running it for a while with all electrics going. Fan all lights wind up and down all windows at the same time.

Cleaned Throttled Body - Ran car until warm - Disconnected battery for 1 min and reconnected - Car back to normal and it didn't cost a cent.THANK YOU EVERYONE FOR YOUR SUGGESTIONS.
