If you dont have any pending codes then it wont be the coils/plugs. vibration at speed is going to almost always going to be something physical. the most common is going to be a tire, especially at speed.

Can you tell if it is front or back? Did the steering wheel also shake/vibrate? Feel it in your butt?
