E-350 Super Duty XLT: I've got a 2012 E-350 with the 5.4. It

Customer Question

I've got a 2012 E-350 with the 5.4. It was running rough and so I brought it in to get scanned and that came back as 3 and 8 were misfiring. I replaced the all the plugs and the coil packs on just 3 and 8 and I'm still getting the same result.
