i fixed the issue on my end, but just threw me codes

i threw my exhaust back on to see if it would make a difference but it didn’t , instead this morning when doing a pull it threw cyl 1-2-3 codes combustion misfire , misfire fuel injection deactivation

it kind of wanted to misfire on the top of the shifts like it gives a sputter or popping noise when i shift but didn’t throw any codes and kept going. again this was at 4am
