wierd AFR issue...
was driving today, punched it, boosted great then i let off and while cruising it was sitting between 12.5-13.5 afr. then at idle it would be around 13.5-14.1. didnt feel rough or anything really...no dying or misfiring that i could feel. tried punching it just to see and it dropped to about 10.5 afr but pulled strong. let off right away as not to cause any more problems. got home, restarted the car and it seems to idle fine. any ideas? very lost lol.
