95 mustang efi to carb swap
I have a 95 mustang was a v6 car has the 5.0 h.o. efi in it bought the car as a mustang gt but didnt know it was a v6 car till i got the title back. I am having problems with the fuel injection and ignition I have replaced every part i can throw at it and it wont run right. I have a f303 cam in the car and got the e7 heads worked and stronger springs in them. that didnt help new mass air, new distribitor, coil, wires ,plugs, fuel pump, fuel pressure regulator, fuel filter even replaced the computer. It runs ok till about 4000rpm then it just busts up only way it seems to pull is with the spout out of it. Im just tired of working on it and no results. So what all is needed to swap out the efi to carb. Been looking at the wieland stealth intake and i got to get a carb. But what else is needed just need to know what direction i need to go in thanks

someone told me the reason its running rough is because its missing the back o2 sensors but dont they just relay temp to the computer? i replaced the 2 upstream o2 sensors think i just want to know what all is needed for the carb swap this efi stuff is too much trouble and have to have a chip and dyno for any little thing that you do to them

codes are :122,157,212,311,314,327,332 but notice its more of a problem at wot not if you ease into it. As far as the o2 sensors my car has upstream o2 sensors which are right by the headers then the downstream are supposed to be behind the cats and they are not installed or even there just wires hanging
