The problem is that when the car is idling, there is a vibration (which is also audible) of the engine and slight rpm drop of maybe 100-200 all within a second, maximum two seconds and then it returns to normal.

I cannot consistently recreate the problem, it comes and goes, but it seems to happen more when I "do" something while in idle like switching to D or R and holding the brake, and or steer in place. Or simply driving and then stopping at a stop light while holding the brake.

What's been done to the engine so far?

First thing to do: Check codes
