I have a question regarding idle currently i noticed when i run my car for a decent period of time (its FI) and i come to a stop after a long cruise at lets say a stoplight my afr jumps up to lets say 16 for a millisecond then drops back to the normal idle afr range as well as my rpms dip low and car shutters for a second then becomes normal again. I know the AP can control idle does anyone have any information regarding maybe correcting or investigating idle through race tuner and making sure it looks normal when its a 0% load maybe i can just set it at 800rpms because that seems pretty safe and not in the danger zone for the car to possibly shutoff.
