He does what he wants – says to himself: he just went out…

Hello So, today something strange happened to me with my Fiesta 1,1 50 Ps BJ 95. I had the week vacation and wanted to drive like the past days also to the butcher and get something for lunch, There it is. I start the little one, wait about 5 seconds insert the forward passage and drive, after about 2 meters he started to jerk after another 2 meters he just went out…. Now I stood there in the middle of the road and tried to read it again at the end of the start process he tried to jump a few times only hardly I stop with the start he tuckers 2 seconds with 500 rpm and then goes out again…. Then a friendly person came and pulled me back into the yard…. I then took off the air filter box and the one vacuum hose (not the one from the Kurbell shaft housing ventilation but the other) and there a 8er Imbus started him and he went, so he then jumped so well wi I could drive again and again. He’s never done that before, and I don’t know if my method with the imbus has succeeded…. Today there’s actually no particularly cold bad or similar weather that can rhyme me why he didn’t want to, now he’s also going again… Oh yes, the spark plugs, the air filter and the gasoline filter don’t have 10 000 km on it yet. Do you know what that could be? Have no pleasure at all if it’s back again Thank you already in advance for your reply! Greetings
