Question: knocking, backfire, losing fuel pretty fast

Hi everyone, i got a 98z71 5.7L vortec. I came up to a light and it started to idle rough and i heard a knock and some backfire. At higher speeds it wasnt as bad but it still wasnt running right. Got home and noiced me fuel went pretty fast to. It dosent knock in park just rough idle....Need help please. Been told it could be a lifter, fuel pressure regulater, intake mainfold leak or knock sensor.. I got codes p0141, p0161, p01380,p0300.. So if anyone has any ideas, that would be great. Thanks a million..
