On these vehicles it's usually a dirty throttle plate. As weird as it sounds a dirty throttle body causes it to stall when or when the AC isn't on. What you have to do is remove the intake and get to the throttle body, remove 4 10 mm nuts and the wiring that controls the motor in the throttle body, then remove the throttle body. For this use a spray made for throttle bodies and nothing else since it's an electronic throttle body. Clean it with a rag then install the throttle body back on and just snug up the nuts, you don't wanna strip them.
