Runs great smooth, but went I start it up and have to put my foot on gas n idles very low (420-500)IT will stall if AC is put on or trying to parked her. This just happened all of the sudden. I just cleaned TB last week as recommended. Also, no check engine light, but it does work. Any ideas?

This happens after the battery was disconnected or run dead. The Engine Computer needs to relearn "minimum throttle" before it will know when it must be in control of idle speed. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the pedals.
