Hey guys,

Just very recently my 530i has developed what seems to be a rough idle, mainly when the car is warm. Only shows a rough idle, drives and pulls fine.

Preventative maintenance has always been done
-new intake gaskets 2 years ago (less than 15,000miles)
-new vacuum lines for EGR, check valves, etc

I'm going to be changing the spark plugs whenever I receive them from delivery. Going to be using original plugs. Currently In it is Bosch Platnium +4's that have been in the car for a few years now, but with no issues until the past few days.

Idle changes when the mass airflow sensor is disconnected (assume its working fine?)

Idle slightly changes, but car runs rich (by smell) when the ICV is disconnected, This might be a possible culprit.

The motor mounts are not old, but I do need to inspect them. Last I checked they were fine.

I might change the coolant temp sensor just for preventative maintenance.

Any ideas or other suggestions on what to check?

thanks in advance.
