Welcome to Bimmerfest! I've moved your question to our X3 forum, you'll get more help in here. Any diagnostic codes?

Have they checked any error codes or checked the ignition coils?

No codes and yes they said replaced all the injectors (probably not) and said coils are fine

If they replaced all the injectors, it may have something to do with the fuel system. I would take it to another dealer and get a second opinion.
