Try cleaning your idle air control valve. Here is how to:

step one: locate your IACV .It is on the intake manifold near the throttle body,

Step two: remove it, all you need to do is take the 2, 12mm bolts out, disconnect the electrical connection, and your heater lines that run to it. (note put a rag on the heater lines so it doesnt spill everywhere)
Step three: take some brake cleaner or carb cleaner and spray out the screen.

Step four: Let it dry, then reconnect your electrical connection, your heater lines, and your bolts.
Hopefully that should fix it.
