This car has P0171 error code.
This car when you re driving at high speed and take off your foot from the gas pedal without pressing brake, the car will stall, now when you press the brake quick FRom high speed, the car rpm will also fall down and the engine will stall.

Now when you slow down before a traffic, I mean when you see issue far away like 200 meters, before the target, the car won’t stall. Idle volve is fine, I have changed plugged
