Engine feels like it's misfiring when in neutral and holding the throttle at 1-2k RPM

[Harry Da Hamster]

I noticed today when i hold the throttle at between 1-2k RPM while in neutral, the engine feel a little rough as if it is almost misfiring. It's not an obvious misfire and it's almost hard to notice. Anyone notice this? Normal? Or do my plugs need to be changed or something?

Totally normal. My e46 did this as well as both my e90. It's a very slight shudder when idling around the rpm you said.

Also it's not missing, but seems more like harmonics of the motor

That's exactly what i was thinking. She runs perfectly otherwise.
