Help with check engine light

I took my Gst to Discount Auto Parts to have my codes checked. The car is throwing the throttle postion sensor and idle control sensor. My friend who worked there tried reseting the code with the plugin and it wouldn't let him. Does anybody know what my problem is or how I can fix this

just like it says. Youve got a bad throttle position sensor or idle air control sensor. They are located on the throttle body. Just try and replace them. Its easy and i cant see them being too expensive.
