    It could be the "Throttle Actuator" is popping the code. From everything I've seen, the 2007 does not have a Throttle Position Sensor, which would be the normal train of thinking. First thing I would try, if it were me, is to take the air intake cover off of the throttle body, and spray some good throttle body cleaner inside, making sure you hit the sensor areas to remove all the carbon built up inside. This may very well take care of the problem, and save you quite a few clams to boot. It might take a few cycles to clear the code, so you could either take it back to Auto Zone and have them clear it, disconnect your battery for about 10 minutes, or just drive it and see if it clears itself over time.

    I have the same problem they told me to clean the throttle body or get a new one to solve the problem.

    Cleaning the TB is fairly straight forward and simple. If you have carb cleaner, some tools and some free time it's pretty simple. Otherwise a new TB is around $80 I believe on Rockauto.
