Engine shake in idle

[testdis]

Hey all. Trying to get some suggestions regarding problem with 2.4 2011 Nox. The engine is idling very rough after a trip on the highway. The engine shakes every so often and the RPM's will fluctuate. This ONLY happens when stopped and idling in drive (at red light). In park or neutral the issue doesn't exist. No power loss and runs fine otherwise. Spark plugs, VVT solenoids and most recently the timing chain was changed. No error codes being thrown. Mechanic can't come up with any other ideas. Any ideas to assist a fellow NOX owner. Thanks all! Jon

If no error codes and not shaking on N or P, maybe a motor mount?
