91' NISSAN 240SX. Engine just started vibrating at idle and when
giving it gas. It kinda smooths out as the RPMs get higher. No noise
at all other than the vibration. It rocks back and forth from left to right.
Can't see anything visually that would cause this.
Does anyone have an idea of what it might be?
I'm thinking one of the spark plugs is bad and causing one of the
cylinders to mis-fire.
Any help would be appreciated.

I think you might be right. It might be running on three cylinders.
Could be plugs or wires.

That's only one reason.
Bad plug, bad wire, bad injector, dirty gas filter.
