Just a thought, have you checked the coil pack for issues? I've had a single coil pack (one pack to fire all 6 cylinders) in an 03 F150 go bad on just one cylinder, and it showed all the symptoms you describe. I tested it by removing the spark plug wire and holding it close to the coil pack (use caution and avoid an electrical shock!). Good luck! - David

Yea I took the plug wire loose and put the old plug in it and laid it on a ground and it sparked. Didn't know if the coil pack could be bad and spark at the wrong time, like maybe jumping internally from another cylinder or not. Never had this much trouble with a misfire before!
