2009 adui a4 2.ot misfiring need help
Need someones input here. Just bought an 2009 adui a4 2.0T quattro and value cover gasket was leaking badly so I replaced it.

Still after all that it misfiring badly during all these issues the cat did get red hot a few times but isn't now anybody go any ideas I'm stuck here and as an autobody technician trying to save money I'm lost here
