I have seen people saying how their cars vibrate on idle. Mine does the same but it’s because I have adjusted above from +25% to -12.5%.
The vibrations may not necessarily be due to engine problems, it maybe due to fuel trim ratios.
Mine is a 2003 corolla nze

If not spark plug, mostly bad air/fuel ratio sensor if idling rpm is low. broken engine mount could also cause take off vibration.

Check also your PCV valve (Permanent Crankcase Ventilator).
When it’s dirty, it has a tendency to cause that.
