88’ LX-i hatch … major vibration at idle

1988 Honda Accord LX-i Hatchback
211,000 miles
5 speed manual
Recently purchased from original owner.
Dealer maintained. Tons of service records.

Just put new plugs (gapped per shop manual)
Oil change as well with filter.
Distributor o ring replaced and timed per shop manual (15 degrees at idle).

When idle the entire car vibrates but the steering wheel is the worst.
Vibrated before and after recent work done.

Any idea what’s going on?
Motor mounts?

What is you idle speed at warmed up?

Hopefully its just low idle but besides the motor mounts being bad its possible there is a bad cylinder in the engine.

Front most and rearmost motor mounts are my guess. My car suffers from the same thing but it's not bad enough to the point where the car seems like it's vibrating itself apart at least.
