Hey guys I recently helped my friend out with his car 2009 335xi car has 86k. He had a misfire on cylinder 3,6 (p0303,p0306 codes). We decided to replace all spark plugs and replace 2 new coil to cylinder 3 and 6. After that no problem, but this morning he txt me and said the problem has occur again. When he started his car early morning which is cold around 6am he said same codes came up. Can someone please help us out any suggestion???

Same two cylinders? Post this in Engines forum.

If he is still misfiring in those two cylinders it may not have been caused by the coil/spark plug. It might be an injector issue.
