Lupo arranges forever – starts very badly – what mistake??

Hello, my girlfriend drives a Lupo Built. 2004, 50 HP 1.0l. For a few days he starts miserable, you can always org until the engine wants to start gradually. Now I couldn’t read out a mistake with my reader?? Can someone help me before I have to go to the workshop? Friend doesn’t have any money anyway. Thanks for the answer!! Greetings, Franky
