So you have your answer.. It needs at least one injector.

i feel dumb, i switch number 7 injector to the number one which is not misfiring, put it all together and started the car, still flashing check engine, scanned it and only code says p0300 random misfire detected.

did live data and turns out number one is now misfiring and number 7 is no longer misfiring

Why the hell do you feel dumb? If not every single member of this forum, I'd bet a huge majority learned from something like this. And I would posit none of them is dumb. Think of it this way: How do you know what you don't know? You learn it from people who do know. And you are blessed with a forum where people actually care about the members knowing.
