on 12v where is your idle set in park with no acc. on??? what hash mark?? I set mine at about 875 and locked the nut and it was fine. I ran the air yesterday and I had to nail the throttle and now it idling at @775 and drops down to 600 with ac on. I stalled twice and my brake pedal is very hard. I assume the nut lossened up but I cant see how
THANKS
