Originally took truck to ford the said the engine was shot so I replaced engine and it still did the same thing found the cats to be plugged changed the and it ran a lot better but still get p2195 p2197 p0171 p0174 p0300 and p0301 and p0305 the truck will idle for a bit than stall almost the same pattern every time,seems to miss intermittently,I have checked for vacuum leaks ,changed MAF ,changed fuel pressure regulator,even changed the plug cop and injector on cyl no.1,swapped fuel pump module from another to see if that was a problem and it didnt change anything,any help would be greatly appreciated
