you need to do you idle learns with the car in drive to load the engine as it would be pulling up to a set of lights.
Set the fc1 rpm to 1100rpm.
make sure your Fc 2 is set around 1200rpm otherwise the
ecu may not catch the rpm in time to stabilize the idle at about 950rpm (set in idle 2) with the additional a/c loading.
Set idle 1 to 900 rpm.
