Falurez

So I bought a 99 f150 5.4 with a misfire guy had a print out said cylinder 5 and 7. I was able to drive it 90 miles back home, also drove it around for a few days 180 miles on top of 90.. then my coils came in and my plugs auto lite plugs.. I install them now it don't wanna drive at all try's to stall out as soon as I put in drive no power i can full throttle it and get it to drive but it's not practical.. I replaced all 8 coils and plugs nothing fixed anyone have any ideas?
