The codes popped after I swapped out my brake pads and rotors but that clearly has nothing to do with it. Could be worth noting that the long tube headers have no cat converters and to prevent codes, the previous owner has extensions on the O2 sensors.
Thanks I'll give those a check, the car popped codes a while back but I don't remember the exact codes but I'll give an update once I check them again. I drive as tame as possible honestly, the codes randomly popped up one day after replacing my brake pads and rotors...
I have a 2016 5.0 with a whipple supercharger (whipple tune), borla long tube headers and a catback system. For a while now, when the car starts up, the needle bounces around at low revs and the car sounds like it's about to turn off, then the revs kick back up to normal after maybe 10 seconds...
