I've got this car few years. Symptoms were sudden.

I will check cold start injector tomorrow because now I don't have much free time but I made simple test. I have blinded by screw fuel hose which is going to this injector and it didn't change anything so probably that is not a problem (but I will check it tommorow). Now car don't want to start at all (it's cold). When I relase the key it starting to waking up and a lot of smoke is going out of throttle body... Probably tommorow it will start without any problem... :/
