If I turn my heat on or air conditioner on when Im in park the truck begins to idle extremely low and then will stall. Although, if Im driving and turn the heat or air on there are no problems. Until I come to a stop or traffic light it just stalls again. I did have a dead battery and replaced it a few months ago so Im wondering if it has something to do with the idle memory. I tried to re-learn the idle memory by going through the steps in a manual and it did NOTHING.
Please help.

I would disconnect the battery and let it set for 10-15 minutes. Then reconnect it and try the idle relearn again.
If no joy, have a good scan tool put on it and clear the ECM. Then it can relearn the crank/cam signal and the idle.
