Hi guys, sadly my first post on here is not a good one, my 2012 (62) 116i started to misfire 2 days ago with no warning light coming up on dash, ordered 4 spark plugs and swapped them out hoping that they might have been the issue. Now the car doesn’t sound/feel like it’s misfiring but doesn’t seem ...
