To start my Stratus 98

Hello everyone, I hope someone can help me, the problem of my Stratus 98 is that to start it (not to turn it on), but to start it, it tends to go out, but it does not go out, but it starts like coughing, and if you do not floor the accelerator thorough It is fine, the only detail is that, not to mention when I reach a semaphor, stop it, vibrate a lot and to start, again the cough, that does not happen if I start it with the accelerator thoroughly, it starts well. greetings

You must check if in Relay it is in three cylinders, and if not you will have to check if the mixture is correct, that is to say that it does not drown because of an excess of fuel.

Hello, I really do not understand what you mean with relief and how do I know if the mixture is correct, please explain to me ... thanks
