Hey guys. First post here.. I have an 07 e60 525i 6speed manual 65k miles that has been sitting for a few months just started her back up.. starts fine then rpms jump and gets rough for about ten seconds then settles in at 600 rpms idle.. and runs perfectly.. any ideas as to the rough start? Thanks in advance

My '06 530xi does the same thing. My research found it's common on the earlier N52 engines but I don't remember when the design was modified to correct it. A couple of bottles of Techron might help it.
