: Yes Steve , I should have mentioned it is an M50 without vanos. 1992 model 525i

The term 'rough' is of course relative and I don't know how bad yours is but I have a 1992 E36 325is (same lump as yours) 121k miles and a 1991 520iA 80k miles both with pre vanos M50 engines and both currently with a clean bill of health, recently serviced and with full main dealer service history.. I would say the idle is certainly uneven and they are known for it.

I think should check idle, fuel and ignition components first before looking at engine mounts.

Good luck.
