Have a 5speed manual 5.4 triton V8 changed coil pks on cylinder 1, 2, 5, 6 .

(1999 Ford F-250 Super Duty)
Had performed diagnostics on it 3 days ago but showed no code .nothing. but the engine isnt firing on all cylinders. Had replaced all plugs amd wires gapped to specifics. Still wasnt firing on all cylinders. So had ordered all new coils from jegs.com and after replacing 1, 2, 5, 6 the truck would shut down . Acting like it wasn't getting air to the engine. What is the most common valveb in the 99 f250 super duty 5.4 5 speed manual? 2 or 3
