Hi guys, had a misfiring cylinder and error codes PO204 and PO304 which relate to injector circuit on cylinder 4. I replaced the injector and it didn't fix the problem. I came back and checked the injector electrical connection and there is fuel in it which obviously isn't good. I didn't touch cylinder 1 and there is also fuel in that connector as well. No fuel is leaking from the injector itself and everything looks as it should. I have attached a photo to the forum post in this link

Thanks for any help, really confused!
