How to Clean Carbon Deposits in Vitara

When coming to a stop, the idle speed suddenly drops and it feels like the car is about to stall. This occasionally happens when shifting from D to P while stationary. I've replaced the spark plugs, ignition coils, injectors, high-pressure fuel pump, PCV valve, carbon canister solenoid, air flow sensor, and engine mounts. I've also cleaned the intake carbon deposits and combustion chamber carbon deposits. The problem still exists. Can anyone help me figure this out? [crying][crying][crying][crying]
