Default AEM FIC running rich when i stop

Can anyone help I want to get my car tuned but dont have the time right now. It runs pretty good but when I go from any gear to a stop it hits 10.0afr for like 5sec then goes normal.

that's completely normal when the bov dumps to atmosphere. As long as ur car doesn't die when that happens, ur golden. If it does, richen up the idle area under 500 rpm. It sounds contradictory, but when u go that rich the ecu pulls a lot of fuel to make it right and sometimes takes too much out and the car could stall. Also if ur regular idle area is borderline rich it can worsen those symptoms.

My idle is pretty good its just when I come out of gear to idle it hits real rich the idle does drop to like 450-500rpm but then goes back up.

With the AC on it doesn't have this problem it just goes right to a normal idle.

Yep, u got it its not ready for speed with out the 22s. It seems like the only map affecting the idle is the maf table.
