6.4 acting weird.

So I bought this 6.4, throwing a inj 8 code right off threw a new ford oem one in deleted the truck and now randomly at idle stumbles regaurdless of temp cold warm whenever it wants. Shut the truck off and it's fine 100%, has great power wouldn't know there's an issue, also sometimes it throws raw white fuel at idle and when stepping on it. I have a weak low pressure pump which is getting fix (maybe causing the inj 8 code). Now only thing I haven't done was put egr block plates. Need info scared it could be a piston problem but when it's not acting up it runs like a top.
