2010 R/T Classic 6M
I've been having issues with my fuel trims being all over the place but I can't find any leaks anywhere. At idle LT fuel trims are steady from +10 to +12. But once I start driving the fuel trims dive to -20s. Before I go into all the diagnostics I've already tried I wanna hear what some of you guys think is causing this. My tuner thinks it's most likely a leak or something and not a bad tune.
