Jona 0 Report post Posted October 8, 2017 Hey all, My 1991 E30 320i has had a bit of a rough idle recently and I have no clue what the problem is. Where there were some vacuum leaks I've been through and changed the perished hoses, the spark plugs seem to be all good. It drives very well and I have no problems there, there isn't any hesitation. Would anybody have any ideas? Thanks! Quote Share this post Link to post Share on other sites
