General multipla problems

[charlotte18]

Hi i have a problem with my multipla its a 1.6 petrol engine but for some reason it loses power and tries to cut out on me.. it recently had the fuel injectors fixed which solved a problem but now it feels like i am driving a train, chugging along thats if i have any power at all, please can you help me..
