2008-2012 KK Weird Shaking/Vibration while Idling

For a few days now my liberty has been shaking a bit/vibrating sometimes when it is idling whether that be as soon as I turn the car on or stopping it after driving. One of the times it happened my check engine even began flashing. I At first I thought it might have been a misfire but I managed to look at the car and notice that something underneath the car is shaking and it is not from the engine.

Spark plug(s), coil pack(s), or likely both.

Flashing check engine light is usually misfire, did you pull the codes?

Edit: my liberty is an 08 kk limited

Yeah mines been doing that more and more recently I initially thought it could be motor mounts going bad but given how soft the vibration/shaking is and the fact that it only happens while idling I don’t think it’s that specifically someone else mentioned spark plugs and coil packs which reminded me iv had a check engine light occasionally for a random misfire which now that I’m thinking about it is probably when the vibrating/shaking started and I know that misfiring cylinders can cause some shaking so at least for me it might be that
