Do a compression test

Had a compression test done but conclusive

Perhaps you need to make the mechanic clean the throttle or reset the ecu... Mine previously shook when idle and had to reset the ecu

This engine idle works between 520rpm and 540rpm because has the ECO start/stop system for faster fire down and fire up....no problem

Can you write what you change and what you try ? Any error codes? It is a automatic or manual? Share some info :D

Best!
