I checked the ignition coil in the cylinder that's misfiring and you guys installed a brand new one in November so it's good, I switched cylinder 8's ignition coil to cylinder 4 to see if it would follow but now its just giving me a random cylinder misfiring and not pinpointing which cylinder. Could it be the spark plugs? ( I have the wrong brand spark plugs in the truck) could that be causing it or could it be faulty fuel injectors?
