i have changed coil pack, plugs, plug wires, is not losing water no bubbles in radiator....
misfire on #2 cyl. sometime run smooth then skips on 2008 Ford Explorer
Going along with goodguy and that guy wetry, if plugs are OEM , and it's SPECIFICALLY a #2 misfire only , then if plug is not misfiring due to oil fouling , you maybe could try swapping injector to a different cylinder to confirm that it's the injector , not an internal problem? wetry might call me an idiot , but thats only because I like green jelly....................Don't underestimate the power of a plug to give you good info. on the problems cause!
