I reflashed my ecu with a modified tune and the problem completely went away I didnt even adjust the fueling in the areas that was previously lean. Now im getting a weird P0403 code every time the car starts up. I monitor for misfires after startup and there is none. I tried another reflash to see if that would do anything and it didnt change anything im confused on why I would only get the misfire code for cylinder 3 on startup and see no symptoms.
