Engine starts rough

Hey guys for the past few months my accords engine has been starting really rough and shaking the whole car when it starts. I can feel when the engine kicks on while i’m driving and it’s very noticeable. I took it to my local dealer and they told me “oh it just does that when they start” I have been working on cars since I was 6 so I know enough that a normal car doesn’t start that way. I have seen other people saying it’s the fuel injectors so should I bring that up with them I will probably bring it in on my day off next week. Thank you for the help in advance :)
