When you take your battery out and put a new one in all your computer controls have to be reset. You need to drive the car at 55 MPH for 2 min or so, stop, go through normal drive cycle, stop and go and then if it don't straighten out you need to clean the throttle body and the idle air control valve. Hope this helps. PHil

I would check the EGR if your car has one it could be sticky, A Renault laguna we had did the same thing, died when letting it down to idle but would
recover, or when it died it would run fine on idle when restarted.
EGR was sticking on it. Vacuum lines could also be an issue.. EGR need vacum to work properly. Trotle body could also be worn, but normally that gives you an uneven idle.

Engine stalls cold or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.
