I have a 2013 Duramax with 148k miles. I have taken very good care of it with routine oil, air and fuel filter changes. When I remote start or start with no throttle, it dies. When I started answer use a little throttle it runs rough. If I start and use moderate throttle it does just fine. I read on another post about the dying issue could be caused by the factor bleeder screw being cracked. I replaced it with a billet one. It seems like it is getting worse. Any help wouldbe great.
