I recently have bought cultus 2007 EFI, after initial tuning the car is working fine except one issue which my mechanic is not able to resolve.
While car is running no matter in what gear, I release accelerator to put my foot on brakes, the RPM drops to ZERO and engine goes off which I immediately restart and it restarts on half self always.
Car is on Petrol CNG is not installed, when mechanic scan with a scanner for error codes, it shows no error and mechanic says car is perfect mechanically.
