Shaking and boggish
I have a 2004 lariat with the 5.4 truck started shaking at idle and accelerating but not all the time, it runs sluggish if I accelerate quickly but if it's not shaking and accelerate gradually it is fine until I hit 140km/h then the engine light starts flashing, I replaced all the coils, when I put the code reader on it tells me misfire on cylinder 4 and misfire on 1000s revolution, is this just the symptoms of bad plugs or something else?
