Hi, I have Suzuki Alto 2010, When the car is driven and idle,Engine choked until he almost turned off, and again returns to normal And so it repeats itself with the engine idling
Black crud accumulates around the butterfly in the throttle body and also in the passages of the idle air bypass.The engine is designed to catch a low idle/ higher load condition (like A/C cycling) and adjust the air that is bypassed so it wont stall. This crud buildup restricts the normal amount of air that the computer is programmed to expect. The program in the computer uses other sensors to see what is actually happening like rpm and trys to adjust. This works until the buildup becomes too much for auto adjustment. Then the car dies at idle.
Removing the throttle body and carefully cleaning these will give the engine enough air to idle. Use a new gasket when re-installing.
Remember that electronic pieces on the throttle body (like the TPS) wont like the cleaner so do whats necessary to keep the spray solvent from entering these sensors.

My 1994 GTi was doing the same thing. The car should idle a bit fast when cold, say 1500rpm, due to the auto-choke. However, 2800rpm is too high. I had a look at my throttle system and could not workout how to adjust the auto-choke idle speed seperate from the normal idle. So I reluctantly had it serviced by the agents, they cleaned out the throttle body and adjusted it. It is better, 1900rpm, but still a bit high for my liking.

check for a vaccum hose disconnected,check air filter casing secure

check the throttle position sensor. that should be whats wrong.

Bad fuel, water in the fuel, dirt in the fuel.
Drain the fuel tank completely.
Pour in a gallon or two of fresh fuel.
See how it goes.
Put some of the old fuel in a glass bottle, hold it up in front of a light and see if you can see any foreign material in it...
