One cylinder dead---plug wire.
With a flat-four, probably true about vibration....but maybe not. Partially-dead; ie, burned valve, broken valve?
This^ You could have a cylinder down on compression and not know it until it gets checked. In the past I've seen a write up for a failed mag check that ended up with having two cylinders replaced.
