Need some advice from mechanics. I have a Dodge Charger 392 Widebody with around 47k miles. I’m getting a P219A code, exhaust ticking when accelerating 2500rpm+, occasional rough/shaky feeling underneath at higher speeds/RPMS in track mode, and sometimes it doesn’t shift normally on auto mode. Sport mode seems to help a little. I also hear a slight stall/hesitation on startup like a small misfire. No mods besides a mid muffler delete. Any ideas what could be causing all of this? Safe to drive short distances?
