Only the engine goes out

Hello guys I am new in this forum and I hope you can help me with my Daewoo, the problem that I present is when I get to stop in neutral after taking temperature and circulate a time, after stopping it costs about three attempts more or less to start again, I have to accelerate it a little to start, I have changed all sensors, coil, spark plug It doesn't turn on anything. Thanks
greetings

Hello for what you comment you have changed rod things, you would have to check fuel pump, ignition module, distributor capturing coil.

Hello. Friend a consultation your vehicle is with multipunto electronic injection? If so, there is a valve the IAC when this valve fails the vehicle has an unstable slowdown, to start it you must accelerate it to start. Many times this valve should only be cleaned or in the extreme case you must replace it.

I hope the comment is helpful

When does it start well or under performance?

The iac or "step by step" valve for more than new must be regulated, if the optuator closes the air passage the car does not start until you open the butterfly ... just the fuel precion ...
